1.4462 Stainless Steel
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:
- Excellent corrosion resistance
- Good resistance to pitting and crevice corrosion
- 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.
