Super Duplex Steel Forged Fittings are primarily composed of 50% austenitic phase and 50% ferritic phase, with high chromium (19-28%), molybdenum (3-5%), and nickel (4-6%) content. This composition offers exceptional corrosion resistance, particularly in chloride-rich environments. The mechanical properties include high tensile strength (up to 80-100 ksi or 550-690 MPa), yield strength (around 50-75 ksi or 345-515 MPa), and hardness (around 300 HB). These fittings also exhibit excellent resistance to stress corrosion cracking, pitting, and crevice corrosion, making them ideal for demanding applications.
