The composition of Duplex Steel UNS S31803 Buttweld Fittings includes about 22% chromium, 5–6% nickel, 3% molybdenum, and trace amounts of nitrogen, resulting in a well-balanced austenitic-ferritic microstructure. They boast a high tensile strength of around 620 MPa and a yield strength of 450 MPa, along with excellent ductility and fatigue resistance. These fittings are particularly resistant to chloride-induced corrosion and offer impressive mechanical stability, making them perfect for high-pressure and high-temperature applications in harsh environments.
