Super Duplex Steel Stud Bolts S32750 consist mainly of iron, with balanced chromium (24-26%), nickel (6.5-8%), molybdenum (3-5%), and nitrogen additions to improve strength as well as corrosion resistance. This alloy has an outstanding balance of high tensile strength (minimum 850 MPa) and good toughness. The duplex microstructure contains approximately equal proportions of austenite and ferrite, which offers even higher resistance to chloride-induced stress corrosion cracking and pitting. The mechanical characteristics of the S32750 bolts make them highly suitable for high-pressure critical applications where durability in tough conditions is a must.
