DUPLEX STAILESS STEEL

Duplex stainless steel refers to stainless steel in which ferrite and austenite account for about 50% respectively. Generally, the content of less phase also needs to reach 30% at least. When C content is low, Cr content is 18%~28% and Ni content is 3%~10%. Some steels also contain Mo, Cu, Nb, Ti, N and other alloy elements.This kind of steel has the characteristics of both austenite and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance. At the same time, it also maintains the 475 ℃ brittleness of ferritic stainless steel, high thermal conductivity and superplasticity.

The main brands of duplex stainless steel include:2304, 2205, 3RE60, 10RE51, 255, UR47N, Zreon100, 2507, UR52N .etc
