Duplex stainless steel, duplex stainless steel (DSS), refers to the ferrite and austenite each account for about 50%, general relatively less content also need at least 30% stainless steel. In the case of lower Cr content, C content in 18%~28%, Ni content in 3%~10%. Some steel also contains Mo, Cu, Nb, Ti, N and other alloy elements.

This kind of steel has the characteristics of austenite and ferrite stainless steel, compared with ferrite, plasticity, toughness, no room temperature brittleness, intergranular corrosion resistance and welding properties are significantly improved, but also maintain a ferritic stainless steel 475 degrees brittleness and high thermal conductivity, has the characteristics of superplastic. Compared with austenitic stainless steel, high strength and intergranular corrosion resistance and resistance to chloride stress corrosion were significantly improved. Dual phase stainless steel with excellent corrosion resistance, is also a kind of nickel saving stainless steel.

 

Applications:

Used in industries as chemical engineering, petroleum, medicine, food, energy, nuclear power, aerospace, 

environmental protection, boiler, gas, war industry, machinery, ship building and so on.
