Austenitic - Ferrite duplex stainless steel belt

Austenitic - Ferrite duplex stainless steel belt both austenite and ferrite stainless steel belt, the advantages of and superplasticity. Organization in austenite and ferrite accounted for about half of the stainless steel band. In the case of contain low C, Cr content was 18% ~ 28%, Ni content at 3% ~ 10%. Some steel containing Mo, Cu, Si, Nb, Ti, N and other alloying elements. This kind of steel both austenite and ferrite stainless steel with characteristics, compared with ferrite, plasticity and toughness is higher, there is no room temperature brittleness, intergranular corrosion resistance and welding performance were significantly increased, while maintaining a ferritic stainless steel with 475 ℃ high brittleness and the coefficient of thermal conductivity, has the characteristics of superplasticity. Compared with austenitic stainless steel belt, high strength and resistance to intergranular corrosion and resistance to chloride stress corrosion is improved obviously. Duplex stainless steel has excellent resistance to pitting corrosion performance, is also a kind of nickel stainless steel belt.
