Super Duplex Steel S32760 Bolts consist of about 25% chromium, 7% nickel, 3.5% molybdenum, with copper, tungsten, and nitrogen additions. This special chemical composition is highly resistant to chloride-stress corrosion and pitting. The alloy has high mechanical strength and tensile strength of 750 MPa and yield strength of approximately 550 MPa. These bolts also possess good toughness and impact resistance even at temperatures below zero. The dual-phase microstructure of austenite and ferrite in balanced proportion guarantees superior performance in severe environments demanding strength and corrosion resistance.
