Duplex stainless steel has the advantages of both ferritic stainless steel and austenitic stainless steel by correctly controlling chemical composition and heat treatment process due to the characteristics of two-phase structure of bidirectional stainless steel. Duplex stainless steel reduces the brittleness and crystal growth tendency of high Cr voxel steel due to the presence of austenite, while maintaining its excellent toughness and weldability. The existence of ferrite improves the yield strength, intergranular corrosion resistance and chloride stress corrosion resistance of austenite. Read More
