Super Duplex Steel Sheets and Plates are made up of high chromium (around 25%), nickel, molybdenum, and nitrogen, which significantly boost their corrosion resistance and strength. They boast impressive mechanical properties, with tensile strength ranging from 800 to 1000 MPa and yield strength nearly double that of standard austenitic stainless steels. These sheets and plates also excel in impact toughness and ductility, even in freezing conditions. Their robust chemical makeup ensures they resist chloride-induced stress corrosion cracking, erosion, and localized corrosion, making them perfect for demanding and high-pressure environments.
