Fajar Nickel Alloys stands out as a top manufacturer and supplier of Super Duplex Steel Pipes, proudly based in Jakarta, Indonesia. We’ve built a solid reputation for providing durable and high-performance piping solutions, perfect for tough applications in challenging environments. Our Super Duplex pipes are celebrated for their remarkable strength, outstanding corrosion resistance, and impressive longevity. Crafted with cutting-edge technology and adhering to international standards, our pipes find their place in various industries, including oil & gas, petrochemicals, marine, and desalination. At Fajar Nickel Alloys, we prioritize quality, timely delivery, and ensuring our customers are satisfied, both in Indonesia and beyond.
Our Super Duplex Steel Pipes are made from alloys like S32750 and S32760, which boast around 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen, all balanced with iron. This unique dual-phase (austenite-ferrite) structure provides high tensile strength (up to 800 MPa), yield strength (about 550 MPa), and exceptional resistance to stress corrosion cracking, pitting, and crevice corrosion. These pipes maintain excellent mechanical properties even in high-pressure, high-temperature, and corrosive settings. Their weldability, toughness, and durability make them the go-to choice for critical and high-load applications.
