Home > Super Duplex Steel > Super Duplex Steel Sheet and Plates
Elvis Nickel Alloys, located in Houston, USA, is a well-respected manufacturer and supplier of top-notch Super Duplex Steel Sheets and Plates, designed to excel in even the toughest industrial settings. Made from high-quality materials like UNS S32750 and UNS S32760, these sheets and plates boast an impressive mix of mechanical strength, corrosion resistance, and long-lasting durability. Their unique dual-phase (austenitic-ferritic) microstructure provides outstanding protection against pitting, crevice corrosion, and chloride stress corrosion cracking. Meeting standards such as ASTM A240, ASME SA240, and EN 10088, they find extensive use in marine, chemical, offshore, and power generation industries.
Super Duplex Steel Sheets and Plates generally contain 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, along with small amounts of manganese, copper, and silicon. With a Pitting Resistance Equivalent Number (PREN) exceeding 40, they are perfect for challenging chloride-rich environments. These materials can achieve tensile strength up to 800 MPa, yield strength of at least 550 MPa, and elongation of 25% or more, all while maintaining excellent impact resistance in sub-zero temperatures. This blend of strength and corrosion resistance makes them ideal for demanding structural and pressure-retaining applications.

Super Duplex Steel Sheets and Plates are commonly utilized in offshore platforms, desalination units, heat exchangers, chemical tanks, pressure vessels, and marine equipment. Their remarkable resistance to chloride-induced corrosion, acidic environments, and high-pressure conditions makes them vital for industries like oil & gas, petrochemical, pulp & paper, and power generation. They are frequently crafted into components such as tubesheets, tank walls, piping, and support structures. Thanks to their high strength-to-weight ratio, thinner gauges can be used, which helps lower overall material costs while ensuring structural integrity and long-lasting performance.
