Super Duplex UNS S32750/S32760/S31803 ASME B16.9 Fittings 1-48 Inch Stainless Steel Pipe Tee Seamless Or Weld
Duplex Stainless Steel (DSS) refers to stainless steel with ferrite and austenite each accounting for about 50%. Generally, the content of less phases needs to be at least 30%. In the case of low C content, the Cr content is 18% to 28%, and the Ni content is 3% to 10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N.
This type of steel has the characteristics of austenitic and ferritic stainless steel. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, and significantly improved intergranular corrosion resistance and welding performance, while still maintaining iron The 475℃ brittleness, high thermal conductivity, and superplasticity of element stainless steel. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel.
Duplex stainless steel
The first category is a low-alloy type, representing the brand UNS S32304 (23Cr-4Ni-0.1N), the steel does not contain molybdenum, and the PREN value is 24-25. It can be used instead of AISI304 or 316 in terms of stress corrosion resistance.
The second category is a medium alloy type, the representative grade is UNS S31803 (22Cr-5Ni-3Mo-0.15N), the PREN value is 32-33, and its corrosion resistance is between AISI 316L and 6%Mo+N austenitic stainless steel between.
The third category is a high-alloy type, generally containing 25% Cr, also containing molybdenum and nitrogen, and some also containing copper and tungsten, standard grade UNSS32550 (25Cr-6Ni-3Mo-2Cu-0.2N), PREN value 38-39 , The corrosion resistance of this type of steel is higher than that of 22% Cr duplex stainless steel.
The fourth category is super duplex stainless steel type, containing high molybdenum and nitrogen, standard grade UNS S32750 (25Cr-7Ni-3.7Mo-0.3N), some also contain tungsten and copper, PREN value is greater than 40, suitable for harsh The medium condition has good corrosion resistance and comprehensive mechanical properties, comparable to super austenitic stainless steel.
