What sets Duplex Steel bolts apart is their unique dual-phase microstructure, which consists of roughly equal parts austenite and ferrite. Typically, they contain about 22% chromium, 5–6% nickel, and 3% molybdenum, along with nitrogen to boost their strength and resistance to corrosion. These bolts boast impressive tensile strength (620–880 MPa) and yield strength (~450 MPa). Thanks to their duplex structure, they offer exceptional resistance to stress corrosion cracking, pitting, and crevice corrosion, particularly in environments rich in chloride. With remarkable fatigue resistance and weldability, Duplex Steel bolts are perfect for high-pressure, high-temperature, and corrosive conditions.
