Fajar Nickel Alloys is a reputable manufacturer and supplier of Super Duplex Steel Pipe Fittings, proudly based in Jakarta, Indonesia. We provide a diverse selection of precision-engineered pipe fittings crafted from high-performance Super Duplex grades like S32750 and S32760. Renowned for their remarkable strength and exceptional resistance to corrosion—especially in environments rich in chlorides and under high pressure—our fittings find extensive use in offshore, petrochemical, marine, and chemical processing industries. Adhering to global standards such as ASTM A815, Fajar Nickel Alloys guarantees reliable quality, precise dimensions, and timely delivery to clients both in Indonesia and around the world.
Super Duplex Steel Pipe Fittings boast a unique dual-phase austenitic-ferritic microstructure, typically made up of 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen. This specific composition provides impressive tensile strength (up to 800 MPa), excellent yield strength (around 550 MPa), and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. These fittings maintain their structural integrity across a wide temperature range, making them perfect for tough and corrosive industrial conditions.
