Elvis Nickel Alloys, located in Houston, USA, stands out as a top manufacturer and supplier of high-quality Super Duplex Steel Tubing, specifically crafted for demanding applications in corrosive and high-pressure settings. Made from materials like UNS S32750 and UNS S32760, this tubing boasts an impressive mix of strength, corrosion resistance, and fatigue performance. Thanks to its balanced austenitic-ferritic microstructure, Super Duplex tubing effectively combats chloride stress corrosion cracking, pitting, and crevice corrosion. It’s a go-to choice in industries such as oil & gas, chemical processing, marine, and desalination, adhering to standards like ASTM A789, ASTM A790, and NACE MR0175.
Super Duplex Steel Tubing generally comprises 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, along with trace amounts of manganese, silicon, and copper. Its dual-phase (austenitic-ferritic) structure ensures remarkable mechanical strength—with a yield strength of at least 550 MPa, tensile strength reaching up to 800 MPa, and good elongation (≥25%). This tubing excels in resisting corrosion in chloride-rich and acidic environments. It performs reliably in both cryogenic and high-temperature conditions, resisting erosion, abrasion, and stress-related failures, making it perfect for tough operating conditions.
