Super Duplex Steel Stud Bolts are typically produced from grades such as UNS S32750 or S32760, featuring a balanced austenitic–ferritic microstructure. The alloy contains high chromium, molybdenum, and nitrogen, providing outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, these stud bolts offer very high tensile and yield strength—nearly twice that of conventional stainless steels—along with good toughness, fatigue resistance, and load-bearing capability under extreme stress conditions.
