Elvis Nickel Alloys, based in Houston, USA, stands out as a top manufacturer and supplier of high-performance Super Duplex Steel Valves, designed to thrive in harsh conditions where corrosion and high pressure are a concern. Made from premium grades like UNS S32750 and UNS S32760, these valves deliver an impressive mix of mechanical strength, corrosion resistance, and durability against fatigue. Thanks to their unique dual-phase austenitic-ferritic microstructure, they excel at resisting issues like chloride stress corrosion, pitting, and crevice corrosion. You can find them in various types, including gate, globe, ball, check, and butterfly valves, all adhering to international standards such as API, ASME, and ASTM.
Super Duplex Steel Valves are crafted from a blend of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, 0.2–0.3% nitrogen, along with trace elements like manganese, copper, and silicon. This combination results in remarkable yield strength (≥550 MPa) and tensile strength (up to 800 MPa), with an elongation of about 25%. These valves maintain impressive mechanical performance even in extreme temperatures, both low and high. Their outstanding impact toughness, paired with excellent corrosion resistance, guarantees long-lasting durability and minimal upkeep, even in chloride-rich or aggressive chemical environments.
