Fajar Nickel Alloys is a reliable manufacturer and supplier of Super Duplex Steel S32750 Pipes, proudly based in Jakarta, Indonesia. We specialize in delivering top-notch piping solutions tailored for the toughest industrial settings, including offshore, marine, petrochemical, and chemical processing sectors. Our Super Duplex S32750 pipes are celebrated for their outstanding mechanical strength, remarkable corrosion resistance, and excellent performance even under high pressure and temperature. Adhering to international standards like ASTM A790 and ASME B36.19, Fajar Nickel Alloys guarantees precision, durability, and dependable delivery to clients both in Indonesia and around the globe.
These Super Duplex Steel S32750 Pipes are made up of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, creating a well-balanced austenitic-ferritic microstructure. This unique composition provides impressive tensile strength (up to 800 MPa), high yield strength (around 550 MPa), and exceptional resistance to stress corrosion cracking, pitting, and crevice corrosion—especially in environments rich in chlorides. These pipes maintain their structural integrity across a broad temperature range and offer long-lasting resistance to corrosion fatigue and erosion, making them perfect for aggressive and corrosive applications.
