These Super Duplex Steel Stud Bolts are made from a blend of high chromium (around 25%), nickel, molybdenum, and nitrogen, which together provide outstanding corrosion resistance and enhanced mechanical properties. They boast impressive tensile strength ranging from 800 to 1000 MPa, with yield strength nearly twice that of standard austenitic stainless steels. Even in sub-zero temperatures, these bolts maintain excellent impact toughness and ductility. Their well-balanced composition ensures superior resistance to chloride-induced stress corrosion cracking and localized corrosion, making them ideal for high-pressure and aggressive operating conditions.
