Duplex steel tube fittings typically consist of a blend of austenitic and ferritic stainless steels, primarily featuring around 22% chromium, 5% nickel, 3% molybdenum, and nitrogen. This composition provides excellent mechanical properties, including high tensile strength (up to 550 MPa), good ductility, and resistance to stress corrosion cracking. The advantages of duplex steel tube fittings include superior corrosion resistance, high strength-to-weight ratio, enhanced toughness, excellent weldability, and cost-effectiveness in demanding environments, making them ideal for applications in oil and gas, chemical processing, and marine industries.
