These Super Duplex Steel Pipe Fittings are made up of about 24–26% chromium, 6–8% nickel, and 3–5% molybdenum, with small amounts of nitrogen and copper added to boost their corrosion resistance and mechanical strength. Thanks to their dual-phase structure, they achieve a high tensile strength of 750–800 MPa, a yield strength of around 550 MPa, and an elongation of 25%. These fittings also demonstrate remarkable impact toughness at low temperatures and maintain excellent resistance to chloride-induced corrosion and stress corrosion cracking, making them perfect for high-pressure and highly corrosive environments.
