Super duplex stainless steel pipe refers to the material in which the ferrite and austenite each accounted for about 50%, the general content is less at least need to reach 30% stainless steel. In the case of lower Cr content, C content is in 18%~28%, Ni content in 3%~10%. Some steel also contains Mo, Cu, Nb, Ti, N and other alloy elements.

This kind of pipe has both the advantages of austenite and ferrite stainless steel, compared with ferrite, the plasticity and toughness are higher, no room temperature brittleness, intergranular corrosion resistance and welding performance was significantly improved, while also maintaining a ferritic stainless steel 475 DEG C brittleness and high thermal conductivity, superplasticity etc.. Compared with austenitic stainless steel, high strength and intergranular corrosion resistance and resistance to chloride stress corrosion were significantly improved. Duplex stainless steel is also with excellent corrosion resistance, is also a kind of nickel saving stainless steel.
