What is 410 Stainless Steel?

410 stainless steel is known also as alloy 410 and UNS S41000. Alloy 410 is a chromium martensitic SS.

It is able to achieve enhanced mechanical properties when heat treated very well.

What is 410 Stainless Steel Equivalent?

Alloy 410 is almost similar with SS alloy 420. 410 SS has fine mechanical properties and reasonable level of corrosion resistance.

Their major disparity has to do with the carbon amount or percentage in both.

420 contains 0.15 – 0.35% carbon while 410 has 0.080 – 0.150% carbon content.

Designations of 410 Stainless Steel

  • AMS 5504
  • ASTM A 240
  • ASME SA 240

Advantages of 410 Stainless Steel?

Here are some reasons why you should consider this stainless steel for your applications:

Resistance to Corrosion

This alloy resists corrosion of low concentrations where mild mineral, fresh water, mildly corrosive conditions, and organic acids are concerned.

Welding

It comes with very good weldability.

Heat Treating

This process enhances its mechanical features.

Magnetic

Whether it is heat treated or annealed, it stays magnetic.

Lastly, this stainless steel grade the best thermal conductivity.

Disadvantages of 410 Stainless Steel

Machining must be done at slow speed if not tempered or annealed. Usually, this may limit certain machining operations.

Chemical Properties

Good corrosion resisting features.

  • It has the finest resistance to water, air, mild acides, hot gases, steam including chemicals such as nitric acid, ammonia, etc.
  • Higher hardening leads to higher resistance for 410 alloy.

Resistance to oxidation.

  • It continuously resists oxidation up to 700°C.
  • Intermittently, it resists oxidation up to 816°C.

The chemical composition of 410 include:

  • 0.15% carbon
  • 1% manganese
  • 1% silicon
  • 0.04% phosphorus
  • 0.03% sulphur
  • 0.75% nickel
  • Up to 13.5% of Chromium which is the most important element in this 410 concentration.

Physical Properties

410 comes with these unique physical properties:

  • It has a fine outlook and is very smooth.
  • Completely magnetic
  • High strength and durability levels.

Some other information on its physical properties to know include:

  • 1495°C melting point
  • 7.65 g/cm3 density.
  • Modulus of elasticity 200gpa.
  • 9.9 – 11.5°C thermal expansion mean coefficient.
  • Electrical resistivity 570nΩ.m..

Mechanical Properties

  • Annealed 410 attains 65000psi minimum tensile strength.
  •  Comes with a 2% offset yield strength of 30000 psi.
  • Its elongation – 20% in 2 inches
  • Hardness below Rockwell B80.

The properties of 410 changes when it is hardened.

  • Its tensile strength moves higher to 205000psi.
  • Yield offset moves higher to 185000 psi.
  • Elongation – 8% in 2 inches.
  • Hardness goes below Rockwell C40.

Difference between 410 vs 316 Stainless Steel

Compositions

316 SS has molybdenum in its composition while 410 SS doesn’t have this element.

  • Yield strength of 410 is 290 – 580 while with 316 it is 230-850.
  • Chromium stands at 16-18% in alloy 316.
  • For 410 SS, chromium is from 11-13%.

Cost

410 alloy costs lesser compared to 316. This is because 410 doesn’t have molybdenum in its makeup.

Treatment Methods

416 requires heat treatments to gain higher levels of strength. On the other hand, 316 requires cold working to enhance its strength levels.

Resisting Corrosion

Due to the inclusion of molybdenum in the makeup of 316 as well as its higher chromium amounts compared to 410, it has better resistance to corrosion when compared to 410.

Machinability

Machining 316 is easier compared to 410 due to the higher content of carbon in 410.

Weldability

Both can be welded with ease.

Resistance to Heat

Alloy 410 experiences a reduction in its mechanical properties at temperatures 400°C and 580°C.

For the finest scaling resistance, temperatures should be 650°C.

Heat Treatments

Some common heat treatment methods include:

Annealing – Complete annealing can be achieved between 815°C – 900°C temperatures.

This needs to be followed by slow air and furnace cooling.

Hardening – To ensure hardening takes place, ideal temperature must be 925°C – 1010°C. However, follow it with oil cooling and oil quenching. Tempering is done next to ensure current hardening is enhanced.

Welding – Welding 410 alloy is simple, however, heating should be at150°C – 260°C.

When welding is completed, annealing is essential to prevent cracking.

Machining – When 410 is highly annealed or tempered, it gets to that ideal level of machining. This is because machining 410 without tempering or annealing can be quite difficult, particularly if they are hardened over 30HRC.

After machining, decontamination and passivation is recommended highly.
