ASTM 2507 Stainless Steel pipe (ASTM S32750/ EN 022Cr25Ni7Mo4N/ 1.4410)


1.Product Description

    Duplex Stainless Steel (Duplex Stainless Steel, referred to as DSS), refers to ferrite and austenite each account for about 50%, generally less phase content of the minimum also need to reach 30% stainless steel. In the case of low C, Cr content of 18% to 28%, Ni content of 3% to 10%. Some steel also contains Mo, Cu, Nb, Ti, N and other alloying elements.
     The steel has the characteristics of austenitic and ferritic stainless steel, compared with the ferrite, plasticity, higher toughness, no room temperature brittleness, resistance to intergranular corrosion and welding performance are significantly improved, while also maintaining iron Qualified stainless steel 475 temper brittleness and high thermal conductivity, with superplasticity and so on. Compared with the austenitic stainless steel, high strength and resistance to intergranular corrosion and resistance to chloride stress corrosion has improved significantly. Duplex stainless steel has excellent resistance to pitting corrosion resistance, but also a section of nickel stainless steel
