Incoloy: All You Need To Know About The Superalloy

Alloys are an important part of any manufacturing process. With alloys, elements, and materials can be properly mixed, combining the benefits of these constituents and their characteristics. And, over the years, more alloys have become especially popular. 

One of the most prominent alloys available in the engineering space today is Incoloy. Known for its strength and resistance to harsh environments, Incoloy is as flexible as it is varied. In this piece, we’ll look into how the Incoloy material works, what you should expect from using it, and how it compares with other related alloys. 

Definition and Overview of Incoloy 

So, let’s begin with the first and most important thing – what is Incoloy? 

For those who might not know, Incoloy is a metal alloy that covers a broad range of products. Developed by Special Metals Corporation, the trademark name covers a family of alloys that have Nickel as their base material. So, Nickel can pretty much be mixed with any other element – or, a group of other elements – to create an Incoloy alloy. 

Generally, these additional elements – such as Iron, Molybdenum, and Copper – tend to provide an added balance and heighten the overall properties of Incoloy. 

Besides the variance in the Incoloy composition, most Incoloy variants tend to come with impressive mechanical properties, optimal strength, high resistance to corrosion, and more. They are used in different industries, ranging from aerospace and chemical processing to oil and gas and marine. 

Due to their impressive physical and mechanical properties, Incoloy material alloys tend to find their best use in environments where exposure to aggressive, harsh conditions will be given. You would also find a use for the materials in cases where they need to withstand significantly high temperatures. So, for things like making components for furnaces and developing gas turbines, Incoloy heating element alloys also come in significantly handy.  

All in all, the combination of impressive temperature strength, corrosion resistance, and long-term durability means that Incoloy is one of the most popular families of alloys in the market. Use of the material has surged significantly over the years, and with so many variants available, the potential for this material’s use could rise even more over the coming years. 

Composition and Alloying Elements 

As we said earlier, Incoloy is a pretty diverse material. You have different variants of the Incoloy steel, meaning that their properties and compositions won’t be the same for sure. Later, we’ll look into the different Incoloy material properties and options available to you. 

Nevertheless, there are some lines of convergence between all variants that need to be mentioned. Primarily, you can find the following materials in any Incoloy alloy:  

  • Nickel (Ni): As we said earlier, the primary element in any Incoloy material is Nickel. In some Incoloy metal alloys, you could find it constituting up to 65% of the entire Incoloy steel. Thanks to Nickel, Incoloy is able to achieve high levels of high-temperature strength, corrosion resistance, and optimal mechanical properties.
  • Chromium (Cr): Next to Nickel, Chromium is probably the material you find in an Incoloy composition. Generally, Chromium is added to Incoloy alloys to enhance their resistance to oxidation and corrosion. The element provides a protective oxide layer on the surface, helping to optimize corrosion resistance and provide a more resolute frame.
  • Iron (Fe): Iron is another popular element that’s used to make Incoloy. In most cases, it is present in small to medium amounts. Thanks to the Iron content, Incoloy is able to optimize strength and several of its material and mechanical properties.
  • Molybdenum (Mo): While it might not be the most popular, Molybdenum is often included in Incoloy alloys to enhance their corrosion resistance. The downside, however, is that Molybdenum isn’t the most common element to find around. So, due to its content, the Incoloy price tends to rise even more. Nevertheless, the addition of this material helps Incoloy to thrive in environments where reducing acids and chlorides are present.

In addition to these primary elements, Incoloy alloys can also contain other alloying elements such as copper (Cu), titanium (Ti), aluminum (Al), niobium (Nb), and others. The specific combination and concentration of these elements vary depending on the desired properties of the alloy and the intended application.

Once again, keep in mind that you have different grades and variants of Incoloy. From Incoloy 800 to Incoloy 800H and more, each of these grades will come with its unique compositions – all of which allow the grade to meet its requirements. So, before making a purchase, it is vital to understand 

Incoloy Product Variants

Incoloy Bar 

An Incoloy bar is a solid, cylindrical rod made of any of the Incoloy alloy variants. Incoloy bars are usually produced through the process of cold drawing or hot rolling, where the alloy is eventually shaped into a bar form. As you’d expect, these bars can vary in diameter, length, and shape – all based on the manufacturer’s requirements and the intended use.

Just as well, the Incoloy alloy used for manufacturing a bar will most likely determine its specific properties – from high-temperature durability to corrosion resistance and more. All in all, Incoloy bars do well to hold their own in challenging environments and can be very useful in applications where resistance to harsh conditions is critical. 

Incoloy Strip

An Incoloy strip is a flat, thin, elongated piece of metal that is made from the Incoloy material. Produced using hot or cold rolling, Incoloy strips are required to have their thicknesses cut down in order to achieve the proper strip size. Lengths and sizes can vary based on the specifications and requirements, of course. 

Incoloy strips are used in different industries, with the specific amount of Incoloy used in manufacturing these strips being the major determinant of the strip’s properties. All in all, you can expect to enjoy optimal formability, strength, and resistance to harsh environments when working with an Incoloy strip.  

Incoloy Sheet

Also, thin and flat, Incoloy sheets are significantly similar to strips. They are also made with the hot or cold rolling technique, where their masses are cut down significantly to make them thinner and more amenable to the right functionalities. 

When making an Incoloy sheet, the need for precision can’t possibly be overstated. So, depending on the variant of Incoloy you want to use, it is important to have the right proportions while working. 

It is also worth noting that Incoloy sheets can be further processed or fabricated to meet the right requirements and manufacturer’s specifications. So, flexibility is pretty much assured here. 

Incoloy Pipe 

Similar to an Incoloy bar, an Incoloy pipe comes with a cylindrical or tubular frame. These pipes are usually welded, although there are also seamless Incoloy pipes. While the seamless pipes are produced from a solid Incoloy billet, the welded ones are manufactured from the amalgamation of different Incoloy sheet sections through traditional welding techniques.

Incoloy pipes primarily offer the benefit of corrosion resistance and long-term durability, making them especially viable for transporting fluids in different industries. When selecting one, it is important to be mindful of the size, wall thickness, and configurations. 

Incoloy Coil 

An Incoloy coil refers to a tightly wound, continuous length of wire or strip made from an alloy belonging to the Incoloy family. Incoloy alloys are nickel-based alloys known for their exceptional corrosion resistance, high-temperature strength, and other desirable properties.

Incoloy coils are typically manufactured by processes such as cold rolling or drawing. The alloy material is formed into a thin, elongated shape, and then wound into a coil configuration. The coil can vary in diameter, length, and thickness depending on the specific application and requirements.

You should also note that Incoloy coils can be further processed or fabricated to meet the specific requirements of the intended application, such as shaping them into heating elements or integrating them into electrical systems.

Properties of Incoloy

This Incoloy water heater element is one of the major reasons why the material itself is so popular.
  • Oxidation Resistance: Incoloy alloys exhibit exceptional resistance to oxidation, preventing the formation of oxide scales on the surface at high temperatures. This resistance helps maintain the alloys’ performance and extends their service life in oxidizing atmospheres.
  • Weldability and Formability: Incoloy alloys generally exhibit good weldability, allowing for ease of fabrication and joining. They can be readily formed into various shapes, including sheets, bars, pipes, and wires, enabling flexibility in manufacturing processes.
  • Resistance to Creep and Fatigue: Incoloy alloys display resistance to creep, which is the deformation that occurs under prolonged exposure to high temperatures. They also exhibit resistance to fatigue, with the ability to withstand cyclic loading and stress over long periods without failure.
  • Electrical Conductivity: Incoloy alloys possess good electrical conductivity, making them suitable for applications that require electrical conductivity along with other desirable properties.

These properties collectively make Incoloy alloys highly valuable in industries such as chemical processing, oil and gas, power generation, aerospace, and many others where resistance to corrosion, high-temperature strength, and reliability are crucial.

Incoloy: Mechanical Properties

The mechanical properties of Incoloy alloys can vary depending on the specific grade or variant of the alloy. However, in general, Incoloy alloys exhibit the following mechanical properties:

  • Tensile Strength: Incoloy alloys have high tensile strength, which refers to the maximum stress a material can withstand before breaking under tension. The tensile strength of Incoloy alloys typically ranges from around 500 MPa (megapascals) to 900 MPa or higher, depending on the specific grade and heat treatment.
  • Density: The Incoloy density can vary depending on the specific grade and composition of the alloy. However, as a general range, Incoloy alloys typically have a density between 8.1 and 8.4 grams per cubic centimeter (g/cm³) or between 0.292 and 0.303 pounds per cubic inch (lb/in³). It’s important to note that the density of an Incoloy alloy can be influenced by factors such as the specific alloying elements and their concentrations. 
  • Yield Strength: Incoloy alloys have a yield strength, which is the stress at which permanent deformation begins to occur. The yield strength of Incoloy alloys typically ranges from approximately 200 MPa to 700 MPa or higher, depending on the grade and condition.
  • Elongation: Incoloy alloys generally exhibit good ductility and elongation, which is the ability of a material to stretch or deform before breaking. The elongation of Incoloy alloys typically ranges from 25% to 45% or higher, depending on the specific grade and heat treatment.
  • Hardness: Incoloy alloys can have varying hardness levels depending on the grade and heat treatment. They are typically characterized by high hardness values, which contribute to their resistance to wear and deformation. Hardness is measured on the Rockwell scale (HRC), and Incoloy alloys can have hardness values ranging from around 20 HRC to 45 HRC or higher.
  • Impact Resistance: Incoloy alloys generally possess good impact resistance, which is the ability to absorb energy without fracturing. This property allows them to withstand sudden shocks or impacts without failure.

It’s important to note that the mechanical properties of Incoloy alloys can be further enhanced through heat treatment processes such as annealing, solution annealing, or precipitation hardening, which can refine the microstructure and improve strength, toughness, and other mechanical characteristics.

The specific mechanical properties of an Incoloy alloy will depend on factors such as alloy composition, heat treatment, and manufacturing processes. Therefore, it is essential to consult the specific material data sheet or consult with the manufacturer for precise mechanical property information for a particular grade of Incoloy alloy.

The unique properties of Incoloy are what makes it so diverse and flexible as a material. And, these are just a few of the functionalities you can expect from it. Over time, there’s no reason why more practical applications of the material can’t be found. 

Advantages of The Incoloy Alloy 

incoloy use

The benefits of the Incoloy material have already been explored. However, let’s get a quick rundown again to provide some clarity: 

  • Corrosion Resistance: You can count on Incoloy to maintain its physical and structural build against all forms of corrosion. This quality makes them perfect for any environment where the conditions are quite aggressive and optimal reliability will be required. 
  • High-Temperature Strength: It is also worth pointing out the resistance to incredibly high temperatures. Even in the hottest of environments, you can always count on Incoloy’s mechanical properties to remain the same. Incoloy won’t degrade,  and its structural integrity will remain strong even at the highest of temperatures. 
  • Oxidation Resistance: Incoloy alloys have excellent resistance to oxidation, preventing the formation of oxide scales on the surface even at high temperatures. This resistance allows the alloys to maintain their performance and extend their service life in oxidizing atmospheres.
  • Good Mechanical Properties: You can also count on Incoloy materials to maintain strong mechanical properties across the board. From the Incoloy hardness to durability and tensile strength, Incoloy won’t disappoint. All variants of this material will easily withstand mechanical stress and deformation while keeping their form in demanding conditions.
  • Versatility: You can find Incoloy alloys in different grades and variants – each with its own specific features and composition profiles. And, thanks to this, Incoloy variants work in different fields and industries. They can be fabricated, machined, and formed into desired shapes to meet specific requirements as well, ensuring that you get the highest levels of flexibility from the material at a moment’s notice. 
  • Weldability and Formability: Incoloy alloys generally exhibit good weldability, allowing you to seamlessly jin and fabricate them. The Incoloy welding procedure tends to vary from one form of the material to the other, meaning that the Incoloy 800 welding procedure won’t be the same as welding Incoloy 825. Nevertheless, the general family of materials can easily be formed into different shapes without necessarily reducing their properties. This means that you can be as flexible as possible while manufacturing
  • Resistance to Creep and Fatigue: Incoloy alloys demonstrate resistance to creep, which is the deformation that occurs under prolonged exposure to high temperatures. They also exhibit resistance to fatigue, allowing them to withstand cyclic loading and stress over extended periods without failure.
  • Electrical Conductivity: Incoloy alloys possess good electrical conductivity, making them suitable for applications that require electrical conductivity along with other desired properties.
  • Reliability and Durability: Incoloy alloys’ combination of corrosion resistance, high-temperature strength, and mechanical properties ensures their reliability and durability in challenging environments. They can withstand harsh conditions and provide long-lasting performance.

Fabrication and Machining of Incoloy 

In general, the steps for making Incoloy will vary based on the grade itself and the manufacturing methods that are employed in getting this material made. So, machining Incoloy 909 and machining Incoloy A286 won’t necessarily be the same thing. 

Nevertheless, the Incoloy machining and welding process tends to go a little bit like this: 

  • Alloy Design: First, you want to determine the Incoloy alloy you’re creating. This will require an understanding of the different Incoloy variants, as well as their chemical compositions. Just as well, you need to know what you’re making – an Incoloy 800 plate and an Incoloy 825 pipe aren’t the same, and understanding the differences between the two of them will be key to helping you know what works best for you in the long run. Select the appropriate percentages of Nickel, Chromium, Iron, and other alloying elements based on the desired properties and performance requirements of the final product.
  • Raw Material Preparation: Once you know what you need, the next step will be finding the right materials. We already covered the chemical constituents of Incoloy, so this shouldn’t be so challenging. However, be sure to see that the materials are carefully measured and blended to achieve the desired alloy composition. You can check the Incoloy wiki to hel;p provide more clarity on the materials constituents. 
  • Melting: After getting the raw materials, go ahead to blend them and melt them in a controlled environment. Most times, this requires the use of furnaces – whether electric arc or induction. With proper melting, you can ensure that the alloying elements are homogeneously mixed, and that the entire formula is perfectly blended.
  • Alloy Refining: You also need to ensure that the molten alloy is properly refined to remove any debris or impurities. Degassing and other techniques are helpful in this regard, ensuring that the content of unwanted elements and gases is cut once and for all. 
  • Continuous Casting or Ingot Casting: Next, you take the refined alloy Incoloy and cast it into large, solid forms via either an ingot or a continuous casting process. In ingot casting, the molten alloy is essentially poured into individual molds, resulting in the ingot. However, for continuous casting, the molten alloy is poured into a water-cooled mold instead. 
  • Hot Rolling: The results of the casting process will then be heated and subjected to a proper hot rolling process. The manufacturer takes the alloy through rolling mills, cutting the material’s thickness and shaping it into the desired form – whether it’s a bar, an Incoloy 800 flange, a sheet, or something. 
  • Cold Working: The hot-rolled alloy is further processed through cold working techniques such as cold rolling or cold drawing. Cold rolling involves passing the alloy through rolling mills at room temperature to achieve the desired thickness, while cold drawing involves pulling the alloy through dies to reduce its diameter and form wires or tubes.
  • Heat Treatment: The cold-worked alloy may undergo heat treatment processes such as annealing, solution annealing, or precipitation hardening. Heat treatment helps refine the microstructure, relieve internal stresses, and enhance the mechanical properties of the alloy.
  • Final Processing: In some cases, the alloy might also undergo additional processing. From machining and cutting to surface finishing and extra coating, there are several processes that are possible for you. 
  • Quality Control and Testing: As you go along the entire manufacturing process, ensuring that the Incoloy alloy is free of any impurities and can easily meet the right standards is critical. This is what quality control steps help to achieve. These may include chemical analysis, mechanical testing, non-destructive testing, and visual inspections. The point is to test all the features of the material – from the Incoloy immersion element to the material’s physical properties and much more. As long as the Incoloy material is certified to be optimal, the tests are a success. 
  • Packaging and Distribution: Once quality control steps have passed the Incoloy alloy material, you can package it and prepare it for distribution. Manufacturers can label and store the material, then ship it to the appropriate destinations. 

Maintenance and Care of Incoloy 

Incoloy is a relatively easy material to work with. And, maintaining it isn’t such a herculean task as well. As long as you keep the following tips in mind, you shouldn’t have an issue with maintaining your Incoloy alloy:

  • Regular Inspections: If you have an Incoloy material, you want to inspect it regularly to identify signs of corrosion, defects, or damage. This makes it easier for you to repair and fix the material if it gets defective.
  • Surface Cleaning: You should also clean your Incoloy alloy to take out debris or contaminants regularly. 
  • Corrosion Protection: We would recommend applying corrosion inhibitors depending on the environment or application of your Incoloy alloy. These inhibitors improve the alloy’s corrosion resistance and can extend its operational lifespan.
  • Avoid Contamination: While corrosion resistance is high, Incoloy is still susceptible to contaminants. So, take precautions to prevent contact with these substances to minimize the risk of corrosion or degradation..
  • Temperature and Pressure Monitoring: Keep an eye on the pressure and temperature conditions of your alloy to ensure that it is working within the appropriate parameters. Excessive temperature and pressure can lead to damage, so be sure to avoid this. 
  • Proper Handling and Storage: You also want to handle Incoloy components or equipment with care to avoid scratches, dents, or other physical damage.
  • Maintenance Planning: Create a maintenance plan that is specific to the components of your Incoloy alloy, so it is easier to keep an eye on it and watch its parameters.
  • Professional Assistance: If you find that your Incoloy material has suffered significant damage or corrosion, then we’d recommend getting professional assistance to help treat the situation. They can provide proper guidance and help you with the appropriate procedures for handling any unsavory situations. 

Incoloy vs Inconel: Battle Of The Superalloys

inconel tube

Incoloy’s unique physical and mechanical properties have led to it being in a special group of alloys. However, as it continues to see greater popularity, comparisons with others of its kind have emerged.

As you’d expect, Incoloy isn’t the only superalloy on the market. And, as manufacturers, finding the right superalloy for your desired functionality is crucial. This is why many have brought up the Incoloy vs Inconel debate. While both materials are especially similar, it is important to find out how they stack up.

Below, we’ve shared a look into the difference between Incoloy and Inconel. 

Material Composition: 

The first major difference between Inconel and Incoloy would have to be with their constituent materials. 

As stated earlier, Incoloy primarily consists of Nickel, Chromium, and Iron. While these act as base elements (particularly Nickel), you can also find trace amounts of elements such as Copper, Molybdenum, and Titanium. 

The same thing can be said for Inconel. However, the primary difference here is that Nickel tends to take up a more prominent role in this alloy’s composition – usually above 50%, in fact. Thus, elements like Chromium, Niobium, and Iron only serve as alloying components. 

So, is Incoloy ferrous, well, it definitely is more ferrous than Inconel for sure. With a higher number of trace and alloying elements, the Incoloy chemical compatibility is on a much higher scale than Inconel. 

Corrosion Resistance: 

In the Inconel vs Incoloy debate, you’ll find that both materials are quite even on this front. However, Inconel tends to come with higher resistance to a broader range of corrosive environments. 


Incoloy is comparatively easier to fabricate and make than Inconel. In most cases, you’d be able to make Incoloy using the same methods you do for stainless steel. Now, is Incoloy stainless steel? Of course not. But, their comparable manufacturing processes mean that manufacturers have an easier time working with them than Inconel. 

High-Temperature Strength: 

A higher Nickel content means that you would most likely see better strength and temperature resistance from Inconel. These alloys can withstand extreme heat, thermal cycling, and creep deformation better than Incoloy alloys, making them more suitable for high-temperature applications across the board. 


In general, Incoloy alloys tend to find the most common use in industries such as power generation, chemical processing, and marine operations. These are areas where corrosion and heat resistance are especially required. 

For Inconel, heat resistance is the name of the game. As such, for uses like gas turbine and nuclear reactor manufacturing, these alloys are most adept. 


At the end of the day, it is worth noting in the Incoloy Inconel debate which of the materials can easily be gotten. 

Compared to Incoloy, Inconel alloys actually have a broader range of available grades. Like Inconloy, you can find Inconel grades using numbers – Inconel 718, Inconel 600, etc. 

However, it is worth noting that Incoloy tends to be cheaper compared to Inconel. They are also more readily available, so accessibility shouldn’t be much of a problem. For the right price, you will be able to find a supplier – as long as you know you’re paying for high-quality materials. 

For the purpose of debating, it is worth noting that these characteristics could easily change based on the variant of Incoloy or Inconel you’re comparing. So, if you’re comparing Incoloy 825 vs Inconel 625, for instance, the outcomes might be different from when you compare Incoloy 825 vs Inconel 825. An understanding of the different grades being compared should help with making a decision. 

Just as well, other factors that could easily influence the properties of the alloys could include heat treatment processes used, manufacturing methods, and more. To wit, be sure to get a proper consultation with the engineers to help set things straight. You also want to check the material data sheets to get enough clarity before proceeding.

Safety Considerations with Incoloy 

While using Incoloy alloys, it is important to consider the right safety precautions to ensure your well-being. Some safety precautions to keep in mind include: 

  • Material Safety Data Sheet (MSDS): Obtain and review the Incoloy datasheet and material safety guide from the manufacturer. 
  • Personal Protective Equipment (PPE): Wear appropriate personal protective equipment, such as safety glasses, gloves, and protective clothing, when handling Incoloy alloys. 
  • Ventilation: Proper ventilation helps to control airborne contaminants, fumes, or gases that may be released during welding, cutting, or other high-temperature processes involving Incoloy.
  • Heat-Related Hazards: Incoloy alloys can retain high temperatures for a significant period. Take precautions to prevent burns or thermal injuries by using appropriate insulation or heat-resistant gloves when handling hot Incoloy components or equipment.
  • Corrosive Environments: Avoid prolonged exposure to strong acids, alkalis, or other corrosive substances that could potentially compromise the integrity of the alloy.

Emerging Trends and Future Developments 

As technologies continue to change and industries maintain their innovation, there is always the possibility of growth in Incoloy use. Manufacturers and suppliers already use Incoloy for several things, but below are a few potential trends to also keep an eye out for going forward: 

  • Advanced Energy Systems: There is a significant chance that Incoloy alloys will be beneficial in advanced energy systems – from developing solar panel technologies to nuclear reactor systems and energy storage. Many of these applications will be heavy on reliability and high-temperature performance; playing right into Incoloy’s advantages.
  • Renewable Energy Infrastructure: Renewable energy sources are already seeing significant adoption. And, over time, Incoloy alloys could also find use in the space. Manufacturers could use them in developing renewable energy infrastructure, from sea-based wind farms to geothermal energy plants and more. 
  • Sustainable Manufacturing: Incoloy alloys are expected to be utilized in sustainable manufacturing processes. As industries strive to reduce their environmental impact, Incoloy alloys can contribute to energy-efficient operations, longer equipment lifespan, and reduced material waste due to their durability and resistance to corrosion.
  • Additive Manufacturing: Already, we’ve seen Incoloy being used in processes like 3D manufacturing. By making it easier to fabricate complex builds and customize components, the material should see additional uses in fields like medical, aerospace, and more.
  • High-Temperature Applications: One thing you can count on going forward is manufacturers’ desire to push the limits of temperature applications. And, with Incoloy’s unique properties and excellent temperature resistance, there is no telling how much the material could still get used down the line. 
  • Miniaturization and Electronics: Incoloy alloys may find applications in the miniaturization of electronics and microelectromechanical systems (MEMS). Their combination of electrical conductivity, corrosion resistance, and high-temperature strength can enable the development of advanced electronic devices, sensors, and microscale components.
