Elvis Nickel Alloys, a reputable name in the world of industrial fasteners located in Houston, USA, specializes in manufacturing and supplying high-performance Super Duplex Steel Nuts S32750, crafted for the toughest environments. Made from UNS S32750 (SAF 2507), these nuts boast remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides, thanks to their well-balanced austenitic-ferritic microstructure. Built to withstand high stress and corrosive conditions, they come in various types, including hex nuts, heavy hex nuts, lock nuts, and cap nuts, all adhering to standards like ASTM A479, ASTM A276, and DIN 934.
Super Duplex Steel S32750 Nuts are made up of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, 0.2–0.3% nitrogen, along with trace elements like copper, manganese, and silicon. These fasteners deliver impressive tensile strength of up to 800 MPa, yield strength of at least 550 MPa, and outstanding ductility and toughness, even in cryogenic conditions. With a high PREN (>40), they excel in chloride-rich and aggressive chemical environments. Whether forged or cold-formed for added strength, these nuts provide exceptional reliability in dynamic and high-pressure applications, making them perfect for structural and mechanical assemblies in extreme service conditions.
