Fajar Nickel Alloys is a reliable manufacturer and supplier of Super Duplex Steel S32760 Fasteners, proudly based in Jakarta, Indonesia. We focus on crafting high-performance fasteners that are built to withstand the toughest industrial conditions, where exceptional strength and corrosion resistance are a must. Our S32760 fasteners are popular in offshore, chemical, and marine settings, thanks to their impressive resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Adhering to international standards, Fajar Nickel Alloys guarantees top-notch materials, precise machining, and rigorous quality control. We’re dedicated to delivering dependable products and ensuring timely delivery to our customers both in Indonesia and around the globe.
Super Duplex Steel S32760 Fasteners consist of about 25% chromium, 7% nickel, 3.5% molybdenum, along with some tungsten, copper, and nitrogen. This unique alloy features a mixed microstructure of austenite and ferrite, which provides remarkable tensile strength (up to 800 MPa) and yield strength (around 550 MPa). S32760 also boasts excellent resistance to localized corrosion, including pitting and crevice attack in environments rich in chloride. With its high mechanical strength and good weldability, S32760 is reliable in both high-pressure and high-temperature situations, making it perfect for demanding applications.

Super Duplex Steel S32760 Fasteners are widely used in industries that require high corrosion resistance and mechanical durability. These applications include offshore oil and gas platforms, subsea pipelines, chemical processing plants, desalination facilities, and marine engineering projects. They are particularly suited for fastening components that are exposed to seawater, harsh chemicals, and significant mechanical loads. Other uses include structural supports, heat exchangers, and pressure vessels. Thanks to their resistance to corrosion fatigue and long-lasting durability, S32760 fasteners are crucial in critical operations where failure is not an option and maintenance costs need to be kept low.
