All You Need to Know About Acid Resistant Duplex Stainless Steel X2CrNiMoN22-5-3, 1.4462, SIS2377


What is 1.4462 Stainless Steel Grade

The 1.4462-grade stainless steel is an acid-resistant duplex stainless steel with an austenitic-ferritic microstructure. Compared to other austenitic stainless steel variants, 1.4462 stainless steel showcases twice the strength making it ideal for applications that contain weight constraints.


The 1.4462-grade stainless steel has the following properties:

  1. Excellent corrosion resistance
  2. Good resistance to pitting and crevice corrosion
  3. Easily weldable


Why use 1.4462 Stainless Steel

The 1.4462 stainless steel grade possesses the stress corrosion property of ferritic grades, though a bit inferior. Lower nickel content in the chemical composition of the steel keeps it slightly immune from nickel price volatilities and also makes it a more economic option in comparison to other austenitic grades. 


What is the chemical composition of 1.4462 stainless steel?

The chemical composition of 1.4462 stainless steel is:

1.4462 steel chemical element % present
Carbon (C) [Max] 0.03%
Manganese (Mn) [Max] 2.00%
Silicon (Si) [Max] 1.00%
Chromium (Cr) 21.0 to 23.0%
