With the advantages of austenite and ferrite stainless steel, and has the plastic. Austenite and ferrite organization of each account for about half of the stainless steel. In the C containing lower, the content of Cr in the 18%~28%, Ni content in 3%~10%. Some steel containing Mo, Cu, Si, Nb, Ti, N and other alloy elements. This kind of steel with austenite and ferrite stainless steel body characteristics, compared with ferrite, plasticity, toughness is higher, no brittle at room temperature, resistance to intergranular corrosion resistance and welding performance were significantly increased, while also maintaining a ferritic stainless steel 475 C brittleness and high coefficient of heat conductivity, superplastic characteristics. Compared with the austenitic stainless steel, high strength and intergranular corrosion resistance and resistance to chloride stress corrosion is improved obviously. Has excellent resistance to pitting resistance of duplex stainless steel, is a section of nickel stainless steel.
