Duplex Steel Buttweld Fittings are primarily composed of a mixture of austenitic and ferritic stainless steel, with around 22-25% chromium, 4-6% nickel, 2-3% molybdenum, and trace amounts of other elements such as nitrogen. This composition provides excellent resistance to corrosion, pitting, and stress corrosion cracking. Mechanically, Duplex Steel exhibits high tensile strength (up to 620 MPa) and good yield strength (around 450 MPa). It also offers superior toughness and ductility, even at low temperatures. These properties make it ideal for high-stress, high-pressure, and corrosive environments in various industries.
