Elvis Nickel Alloys, a well-respected manufacturer and supplier based in Houston, USA, specializes in top-quality Super Duplex Steel Fasteners S32760, engineered to excel in highly corrosive and high-pressure settings. Made from UNS S32760 (Zeron® 100), these fasteners boast a dual-phase microstructure (austenitic-ferritic), which provides outstanding resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. They come in various forms, including bolts, nuts, screws, washers, and stud bolts, and meet international standards like ASTM A479, ASTM A276, and ASME B18.2.1. These fasteners are known for their exceptional strength and reliability, making them perfect for offshore, marine, and aggressive chemical processing applications.
Super Duplex Steel S32760 Fasteners are composed of 24–26% chromium, 6–8% nickel, 3–4.5% molybdenum, 0.2–0.3% nitrogen, and 0.5–1% copper, along with trace amounts of tungsten, manganese, and silicon. They achieve a high PREN (Pitting Resistance Equivalent Number) greater than 40, ensuring remarkable corrosion resistance in challenging chloride and acidic environments. These fasteners demonstrate impressive tensile strength (up to 800 MPa), yield strength (≥550 MPa), and notable toughness, even at cryogenic temperatures. Their forged or machined finish guarantees precision and durability under dynamic loads.
