Elvis Nickel Alloys, based in Houston, USA, is a reliable manufacturer and supplier of top-quality Super Duplex Steel Pipe Fittings, specifically crafted for the toughest corrosive and high-stress environments. These fittings are made from durable super duplex grades like UNS S32750 (SAF 2507) and UNS S32760 (Zeron® 100), providing an outstanding mix of high tensile strength, excellent corrosion resistance, and a long lifespan. Thanks to their balanced austenitic-ferritic microstructure, they effectively resist pitting, crevice corrosion, and chloride stress corrosion cracking. You can find these fittings in various types, including elbows, tees, reducers, and caps, all adhering to international standards like ASTM A815 and ASME B16.9.
Super Duplex Steel Pipe Fittings generally consist of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, 0.2–0.3% nitrogen, along with trace amounts of copper, tungsten, and manganese. These elements work together to achieve a high PREN (>40), which provides exceptional resistance to localized corrosion. The fittings boast a tensile strength of up to 800 MPa and a yield strength of at least 550 MPa, along with impressive impact toughness, even in low temperatures. Their dual-phase structure enhances fatigue strength and overall structural integrity, making them perfect for high-pressure and chemically aggressive environments.
