Duplex Steel S31803 Forged Fittings are made up of approximately 21–23% chromium, 4.5–6.5% nickel, 2.5–3.5% molybdenum, and nitrogen, all balanced with iron. This unique alloy boasts a dual-phase austenitic-ferritic structure, which delivers outstanding corrosion resistance and mechanical strength. These fittings have a tensile strength ranging from 620 to 880 MPa, a yield strength of 450 MPa, and an elongation of at least 25%. They are particularly resistant to pitting, crevice corrosion, and chloride stress corrosion cracking. Their exceptional mechanical integrity and fatigue strength make them perfect for high-pressure systems and harsh chemical environments.
