Fajar Metals, a trusted name in Jakarta, Indonesia, specializes in manufacturing and supplying top-notch Duplex Steel 2205 Flanges that are designed to excel in tough environments. These flanges boast impressive strength, resistance to corrosion, and stability in dimensions, making them perfect for industries like oil & gas, chemical processing, marine, and power generation. Fajar Metals offers a wide variety of flanges—including weld neck, slip-on, blind, threaded, and socket weld options—all crafted to meet international standards. Renowned for their durability and ability to resist chloride stress corrosion cracking, Duplex 2205 flanges guarantee secure, leak-proof connections in high-pressure and corrosive settings.
Duplex Steel 2205 flanges are made from a carefully balanced blend of chromium, molybdenum, nickel, and nitrogen. This unique dual-phase alloy combines the best of ferritic and austenitic stainless steel, resulting in impressive tensile and yield strength—nearly double that of standard stainless grades. The composition also provides exceptional resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. These flanges are not only easy to weld but also exhibit high fatigue strength and good impact toughness, even in freezing conditions. Fajar Metals ensures precise machining and rigorous quality control to meet mechanical specifications and ensure long-lasting performance.
