Valve body made with duplex stainless steel has excellent corrosion resistant properties. It is widely used in corrosive liquid pipeline systems. Duplex stainless steel combines the characteristics of Austenitic and Ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance. At the same time, it also maintains the high thermal conductivity of ferritic stainless steel, with super plasticity and other characteristics. Compared with Austenitic stainless steel, it has higher strength and significantly improved resistance to inter granular corrosion and chloride stress corrosion. Duplex stainless steel has excellent resistance to pitting corrosion and is also a nickel saving stainless steel.
Main duplex stainless steel grades include S32750 (SAF2507, F53), S31803 (SAF2205, F51), 654SMO, RS-2, XM-19 (Nitronic50), S21800 (Nitronic60), 20Mo-6 (N08026), F55 (S32760), F60 (S32205), 17-7PH (SUS631), 17-4PH (SUS630), 309S, 310S (2520), 347 (S34700), A4, C4, CN7M \ NS1433.
