Super Duplex Steel S32750 washers consist of 24-26% chromium, 6-8% nickel, 3-5% molybdenum, and 0.2-0.3% nitrogen by composition. Also included are small quantities of tungsten, copper, silicon, and manganese.. These materials comprise a balanced duplex structure that provides excellent pitting resistance, crevice corrosion resistance and chloride stress corrosion resistance. These washers are highly durable and capable of providing superior performance under severe operating conditions. The mechanical properties of Super Duplex Steel S32750 washers typically include tensile strength of approximately 800 MPa and yield strength near 550 MPa. Hardness levels for these washers can reach approximately 310 HB and elongation are typically around 25%.
