Duplex Steel Nuts are crafted from a unique dual-phase microstructure that combines austenite and ferrite, typically containing 22–23% Chromium, 4.5–6.5% Nickel, 3–3.5% Molybdenum, and low carbon content. This well-balanced composition endows them with exceptional strength and remarkable resistance to chloride stress corrosion, pitting, and crevice corrosion. These nuts showcase impressive mechanical properties, including high tensile strength (up to 800 MPa), excellent fatigue resistance, and enhanced hardness compared to standard stainless steels. Their metallurgical structure also ensures good weldability and stability in high-pressure, high-temperature, and aggressive chemical environments.
