Duplex Steel Pipe Fittings, usually made from UNS S31803 or S32205, consist of about 21–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen, with iron making up the rest. This unique dual-phase (austenitic-ferritic) microstructure provides exceptional mechanical and corrosion-resistant properties. These fittings boast a tensile strength ranging from 620–880 MPa and a yield strength of around 450 MPa, along with impressive ductility and elongation. They are particularly resistant to chloride-induced stress corrosion cracking, pitting, and crevice corrosion, making them perfect for high-pressure, high-temperature, and chemically aggressive systems in various demanding industrial settings.
