Elvis Nickel Alloys, based in Houston, USA, stands out as a top manufacturer and supplier, focusing on high-performance Super Duplex Steel Pipes S32750. These pipes are specifically crafted to handle the tough demands of industrial, marine, and offshore settings. Made from UNS S32750 (SAF 2507), they boast a unique dual-phase austenitic-ferritic microstructure that provides remarkable mechanical strength, resistance to chloride-induced corrosion, and excellent stress corrosion cracking resistance. Meeting international standards like ASTM A790, ASME SA790, and NACE MR0175, these pipes are perfect for desalination plants, chemical processing, offshore oil and gas platforms, and power generation facilities, where durability and longevity are paramount.
Super Duplex Steel S32750 Pipes are made up of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, along with trace amounts of manganese, copper, and silicon. These pipes showcase impressive tensile strength of up to 800 MPa, yield strength of at least 550 MPa, and outstanding elongation and toughness, even in cryogenic conditions. With a high PREN (Pitting Resistance Equivalent Number) greater than 40, they deliver exceptional performance in chloride-rich and corrosive environments, making them a reliable choice for critical applications that involve high pressure, vibration, and extreme temperatures.
