Elvis Nickel Alloys, located in Houston, USA, stands out as a top manufacturer and supplier of high-quality Super Duplex Steel Fasteners S32750. These fasteners are engineered for maximum strength and exceptional corrosion resistance, making them perfect for extreme service conditions. Crafted from UNS S32750 (SAF 2507), they boast a unique dual-phase (austenitic-ferritic) microstructure that offers remarkable protection against pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. Available in various forms like bolts, nuts, washers, screws, and stud bolts, these fasteners meet global standards such as ASTM A479, ASTM A276, and ASME B18.2.1, ensuring top-notch performance in offshore, chemical, and marine settings.
Super Duplex Steel S32750 Fasteners are made up of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, along with small amounts of copper, manganese, and tungsten. This well-balanced composition results in a high PREN (>40), which translates to excellent resistance against localized corrosion. These fasteners showcase impressive mechanical strength, with tensile strength reaching up to 800 MPa and yield strength of at least 550 MPa, along with outstanding impact resistance, even in cryogenic conditions. Their blend of high strength and corrosion resistance makes them perfect for challenging and corrosive environments.
