stainless steel UNS32750 pipe for shipbuilding Duplex Stainless Steel Pipe Duplex stainless steel has �±+�³ dual-phase structure, so its performance characteristics have the characteristics of austenitic stainless steel and ferritic stainless steel, and it is a kind of stainless steel with high strength and corrosion resistance. Usually, in the case of low C content, the Cr content is 18%~28%, and the Ni content is 3%~10%. Some steels also contain alloying elements such as Mo, Cu, Nb, Ti, and N. Compared with ferrite, it has higher plasticity and toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance. Features. Compared with austenitic stainless steel, the yield strength is significantly improved, and the resistance to intergranular corrosion, stress corrosion, corrosion fatigue and abrasion is significantly improved. Main grades: S31803/S32250, S32750, S32760, S31500, S31500, 32001, S32003, S32304 Commonly used standard: ASTM A789 (ASME SA789) General Purpose Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe ASTM A790 (ASME SA790) Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe ASTM A928 (ASME SA928) Standard Specification for Filled Metal Electrofusion Welded Ferritic/Austenitic (Duplex) Stainless Steel Tubing GB/T 21832-2008 Austenitic-ferritic duplex stainless steel welded steel pipe GB/T 21833-2008 Austenitic-ferritic duplex stainless steel seamless steel pipe Features: 1. Excellent general corrosion resistance and local corrosion resistance, especially stress corrosion resistance, pitting corrosion resistance, crevice corrosion resistance, corrosion fatigue resistance and abrasion resistance, etc. 2. Good weldability 3. Good comprehensive mechanical properties 4. Good resistance to intergranular corrosion 5. High cost performance and long service life UNS S32750 super duplex steel has high strength and excellent corrosion resistance. It is especially suitable for components in desalination plants, heat exchangers in seawater cold treatment plants, drive shafts for outgoing pipes in the ocean, containers in paper mills and petrochemical conveying tube etc. It can also be used in exposed external environments (such as bridges, sea-immersed buildings, etc.) for a long time. Due to their high strength, good plastic toughness, and slower ductile-brittle transition than carbon-steel ferritic stainless steels, dual-phase steels also have good low temperature (-40�°C) toughness. In short, the dual-phase steel material will be an excellent material for engineering applications. Specifications: 6.5-800 Spot storage is available. Available in custom sizes.
