431 stainless steel

431 stainless steel

431 characteristics and applications:

431 (16Cr-2Ni) Ni-containing Cr steel can obtain high mechanical properties through heat treatment and has better corrosion resistance than 410 steel and 430 steel.

431 stainless steel corresponds to China 1Cr17Ni2, Japan JIS SUS431. 

431 chemical composition:
