Fajar Nickel Alloys stands out as a leading manufacturer and supplier of Super Duplex Steel Bars, proudly based in Jakarta, Indonesia. We focus on crafting high-strength, corrosion-resistant bars that meet the needs of industries looking for durable and reliable materials for their demanding applications. Our Super Duplex steel bars are produced to comply with international quality standards, guaranteeing exceptional mechanical properties and outstanding resistance to harsh environments. Thanks to our advanced production techniques and rigorous quality control, Fajar Nickel Alloys delivers precision-engineered bars that cater to clients in offshore, chemical processing, marine, and petrochemical sectors, both in Indonesia and around the globe.
Our Super Duplex Steel Bars are crafted from alloys like S32750 and S32760, which include approximately 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen. This unique dual-phase (austenitic-ferritic) microstructure provides remarkable tensile strength (up to 800 MPa), high yield strength (around 550 MPa), and excellent resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. These bars retain their toughness and durability even in extreme temperatures and corrosive conditions, making them perfect for critical applications.
