Product details

Duplex stainless steel has the characteristics of austenitic stainless steel and ferritic stainless steel because of its austenitic + ferritic biphase structure, and the content of the two phase structures is basically equivalent. The yield strength can reach 400Mpa ~ 550MPa, which is twice that of ordinary austenitic stainless steel. Compared with ferritic stainless steel, duplex stainless steel has higher toughness, lower brittleness transition temperature, and significantly improved intergranular corrosion resistance and weldability.
