History Of Duplex Stainless Steel Development
- Aug 17, 2018 -

Two-phase stainless steel has developed into the third generation since its birth in the United States in the 1940s. Its main feature is that the yield strength can reach 400-550mpa, which is twice that of ordinary stainless steel, so it can save materials and reduce equipment manufacturing cost. In terms of corrosion resistance, especially under harsh medium conditions (such as seawater and relatively high content of chloride ions), two-phase stainless steel has better corrosion resistance, crevice corrosion, stress corrosion and corrosion fatigue performance than ordinary austenitic stainless steel, which is comparable with high-alloy austenitic stainless steel.
