Super Duplex Steel Nuts S32750 consist of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (~0.24–0.32%), and Iron (balance), with small amounts of Manganese (<1.2%), Carbon (<0.03%), Copper (~0.5%), and Tungsten (~0.5%). This even composition provides very good pitting, crevice corrosion, and chloride stress corrosion cracking resistance. These nuts have very high tensile strength (~795–850 MPa), yield strength (~550 MPa), and elongation of approximately 25%. They have a density of 7.8 g/cm³ and thermal conductivity of ~15 W/m·K. They behave well in high-pressure, high-temperature, and corrosive environments.
