Our Super Duplex Steel Valves are made with a blend of high chromium (around 25%), nickel, molybdenum, and nitrogen, which significantly boosts their corrosion resistance and mechanical strength. They boast impressive tensile strength ranging from 800 to 1000 MPa, with yield strength nearly double that of standard austenitic stainless steels. Even in low temperatures, these valves maintain excellent toughness and ductility. The advanced alloy composition guarantees resistance to chloride stress corrosion cracking, erosion, and localized corrosion, making them a reliable choice for aggressive, high-pressure, and high-temperature environments.
