The composition of Super Duplex Steel Tubing includes high levels of chromium (around 25%), along with nickel, molybdenum, and nitrogen, all of which boost its corrosion resistance and mechanical strength. It boasts impressive tensile strength ranging from 800 to 1000 MPa, with yield strength nearly twice that of standard austenitic stainless steels. Even in sub-zero temperatures, this tubing maintains excellent toughness and ductility. Its well-balanced alloy composition ensures outstanding resistance to chloride-induced stress corrosion cracking, localized corrosion, and erosion, making it perfect for high-pressure and high-temperature settings.
