**Super Duplex Steel S32750**, also referred to as UNS S32750 or SAF 2507, is a high-performance alloy made up of nearly equal parts of austenite and ferrite, along with chromium (25%), molybdenum (4%), and nickel (7%). This unique blend provides the stud bolts with remarkable strength and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking—particularly in environments rich in chlorides. S32750 stud bolts boast high tensile and yield strength, outstanding fatigue resistance, and exceptional performance in challenging offshore and chemical conditions.
