Is austenite and ferrite in each account for about half of the stainless steel. In the case of with low c, Cr content in the content of 18~28,Ni is 3~10. Some steel contains Mo, Cu, Si, Nb, Ti,N and other alloying elements. Steel and have the class characteristics of austenitic and ferritic stainless steels, compared with ferrite, plastic, high flexibility, no brittle at room temperature, resistance to intergranular corrosion properties and weldability are significantly improved, while also maintaining a ferritic stainless steel brittle 475 ° c and high thermal conductivity, with Super plastic and so on. Comparison with austenitic stainless steel, high strength and intergranular corrosion resistance and corrosion resistance to chloride stress an obvious improvement. Pitting corrosion resistance of duplex stainless steel with excellent performance, is also a section of nickel in stainless steel.
