Austenitic - ferritic duplex stainless steel pipe fitting

　　Austenitic - ferritic duplex stainless steel: Austenitic and ferritic organizations are about half of the stainless steel. In the case of low C content, Cr content of 18% to 28%, Ni content of 3% to 10%. Some steel also contains Mo, Cu, Si, Nb, Ti, N and other alloying elements. This type of steel combines the characteristics of austenitic and ferritic stainless steel, compared with ferrite, ductility, toughness, no room temperature brittleness, resistance to intergranular corrosion and welding performance are significantly improved, while maintaining iron Fritility of 475 ℃ brittleness of stainless steel and high thermal conductivity, with superplasticity and so on. Compared with austenitic stainless steel, high strength and resistance to intergranular corrosion and chloride stress corrosion resistance has improved significantly. Duplex stainless steel has excellent pitting corrosion resistance, but also a section of nickel stainless steel.

　　We can supply 304/304L,316/316L and 316Ti etc. stainless steel pipe fittings like elbows, bends, reducers, tees, caps, and A182 F55 Alloy Socket welding flanges. Welcome to send us a copy of inquiry we can give you a satisfied reply.
