Cold Rolled Seamless 2205 Duplex Stainless Steel Pipe In Petroleum And Aerospace
Specifications:
Dual phase stainless steel tube has good welding performance, compared with ferritic stainless steel and austenitic stainless steel, it is not like the welding heat affected zone of ferritic stainless steel, due to the serious grain coarsening and the toughness of the plastic is greatly reduced.
Because of its special advantages, duplex stainless steel has been widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil transportation pipeline, paper machinery and other industrial fields. In recent years, it has been used in the field of bridge bearing structure, which has good prospects for development.
Duplex stainless steel is in its solid quenched microstructure of the ferrite phase and austenitic phase of each half, generally at least phase content may be up to 30%.

Description:
Due to the characteristics of the two-phase structure, the DSS has the advantages of ferritic stainless steel and austenitic stainless steel by properly controlling the chemical composition and the heat treatment process.
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.
