Duplex Steel Stud Bolts feature a well-balanced microstructure of austenite and ferrite, packed with chromium (about 22–25%), nickel, molybdenum, and nitrogen to boost strength and corrosion resistance. Their mechanical properties shine with excellent tensile strength, impressive yield strength (nearly double that of regular stainless steels), and high fatigue resistance. Plus, they offer good toughness and weldability, along with remarkable resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, making them perfect for tough environments.
