Advantages of Using Stainless Steel 220

Advantages of Using Stainless Steel 220

You will never go wrong choosing this type of stainless steel due to the numerous benefits it can offer.

The stainless steel grade 220 is a high-grade alloy that offers superior strength and corrosion-resistant properties than other grades. Therefore, it is perfect in a wide range of harsh environments. That is one of its main advantages.

Another is its excellent protection against heat. 220 stainless steel has high chromium content enabling it to withstand temperatures up to 1400 degrees Fahrenheit without losing its structure. For this reason, it is a great choice for fabrication projects requiring high temperatures. Examples are those found in industrial ovens and boilers.

The cost-effectiveness of type 220 also makes it the most preferable stainless steel alloy. Additionally, the stainless steel 220 has good ductility. This is what makes it advantageous for applications that require forming or welding.

And lastly, its low price point makes it an attractive option for budget-conscious individuals and businesses.

The Possible Drawbacks

Like what we’ve learned above, using 220 stainless steel can be beneficial in many ways. But it also comes with some drawbacks and you should be aware of that.

Here are its possible drawbacks.

  • Level of Rust Resistance: The main drawback of using type 220 is its lack of rust resistance. This gives a tendency to gall if not properly heat treated. These are the reasons why it is not recommended for environments exposed to moisture and other corrosive elements.
  • High Cost: The material is more expensive than other grades of stainless steel you can find. And sometimes, it may not be cost-effective for some purposes.
  • Limited Availability: The grade 220 is rare to find and may be difficult to source. It is not as widely available as other grades.
  • Low Strength: The 220-grade stainless steel has a lower strength than others. As result, it is not approved for applications that require high strength.

SS220 Fabrication Methods

There are several different fabrication methods that can be used when working with grade 220. It includes welding, machining, and forming.



The welding method is the most common fabrication method for stainless steel grade 220. This process involves the use of an electric arc to join two or more pieces of metal together. 220 steel is typically welded using the TIG (Tungsten Inert Gas) process, or the MIG (Metal Inert Gas) process. Both methods create strong and reliable welds that are resistant to wear.



The machining method is another popular method for fabricating grade 220. This process involves the use of cutting tools to shape the metal into the desired shape. Machining can be used to produce complex geometries and intricate details. It also offers the advantage of being able to produce parts with tight tolerances and high accuracy.


Hot Forming

The forming method is a process that is used to create complex shapes out of stainless steel 220. This process involves the use of specialized presses and tools to shape the steel into the desired shape. Forming can also be used to create components like automotive equipment, aerospace parts, and medical instruments.

These are just a few of the different fabrication methods that can be used when working with 220-grade stainless steel. Each method has its own advantages and disadvantages. So it is important you consider all of the options before deciding which one to use.

Comparing SS 220 and SS 316

Comparing SS 220 and SS 316

These two grades, stainless steel 220 and 316 have numerous differences.

Consider the following.

Type of Grades

220 is a ferritic stainless steel grade that is often used for general-purpose applications. While the 316 is an austenitic stainless steel grade that is used in more corrosive environments.


Grade 220 is referred to as a “general-purpose” grade because it has a good combination of strength, ductility, and corrosion resistance. It is also slightly magnetic and has a relatively low melting point. Compare to 316, it offers extreme safety against crevice corrosion in chloride-containing environments.


When it comes to cost, 220 is typically less expensive than 316. However, the higher cost of 316 stainless steel is often offset by its superior corrosion-proof and superior mechanical properties.

Tear & Wear Resistance

Grade 316 is more resistant to wear & tear than 220 stainless steel. Then this makes it ideal for applications that require high durability.

Proper Maintenance for 220 Stainless Steel

Proper Maintenance for 220 Stainless Steel

Here are some effective tips for proper maintenance:

The first tip is cleaning. To clean your stainless steel 220, you will need soft clothing, mild soaps, and boiled water. Make sure to rinse thoroughly afterward.

Next is polishing. If there are scratches, remove them and restore the original shine by using a stainless-steel polish. This will help keep the metal looking its best.

Then add protection. To protect your stainless steel from any corrosions and staining, you only need a protective coating like wax & oils. These can help prolong the stainless steel’s life and maintain its great looks.

The last tip is storing. When not in use, store the stainless steel in a dry, cool place. Avoid storing it in areas that are prone to moisture and heat to prevent deterioration.

By following these simple tips, you can help ensure that your 220 stainless steel will remain in top condition for years to come. Regular maintenance and cleaning are essential for keeping the metal looking great while performing its best.
