The composition of Duplex Steel 2205 Stud Bolts includes about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, which together create a balanced duplex microstructure of ferrite and austenite. This unique blend provides high tensile and yield strength—twice that of standard stainless steels—along with remarkable resistance to pitting, crevice, and chloride stress corrosion cracking. Additionally, these bolts are known for their good weldability, toughness, and resistance to oxidation at elevated temperatures.
