Duplex Steel Screws are composed of approximately 22% chromium, 5–6% nickel, and 3% molybdenum, with nitrogen and manganese additions. These screws provide tensile strengths ranging from 620–850 MPa and better yield strength than common austenitic stainless steels. The dual-phase structure gives them excellent pitting, crevice corrosion, and chloride stress cracking resistance. They are resistant to strength loss at high and low temperatures, providing better fatigue strength and long-term performance. Mira Fasteners puts every duplex screw through rigorous testing for metallurgical soundness and mechanical performance.
