Super Duplex Steel S32750 is an austenitic-ferritic stainless steel alloy with a high chromium, molybdenum, nickel, and nitrogen content. It contains about 25% chromium, 7% nickel, 3.6% molybdenum, nitrogen, and smaller amounts of other elements such as manganese, silicon, and iron. The high chromium and molybdenum content provide excellent resistance to pitting and crevice corrosion, while the nickel content enhances resistance to general corrosion. The high nitrogen content contributes to the alloy's mechanical properties and high strength.

S32750 SD Steel screw is austenitic-ferritic stainless steel that offers high strength and resistance to corrosion. It contains 25% chromium, 7% nickel, 3.7% molybdenum, and other elements such as nitrogen, manganese, and iron. The high chromium and molybdenum content gives the S32750 screw excellent resistance to pitting, crevice corrosion, and general corrosion in a wide range of media. The addition of nitrogen enhances the mechanical properties, making it suitable for high-stress applications. The Duplex Stainless Steel S32750 screw has high tensile strength, excellent creep and stress-rupture resistance, and excellent flexibility, making it ideal for use in high-pressure and high-temperature applications. It is widely used in the oil and gas, petrochemical, and chemical industries, as well as in desalination plants and heat exchangers.
