Fajar Nickel Alloys stands out as a top manufacturer and supplier of Super Duplex Steel S32750 Flanges, proudly based in Jakarta, Indonesia. We’re recognized for our high-performance piping components, crafting S32750 flanges that boast remarkable strength, corrosion resistance, and durability. These flanges are specially designed to thrive in tough environments, such as offshore platforms, chemical processing facilities, and marine systems. Adhering to international standards like ASTM A182 and ASME B16.5, our Super Duplex flanges are known for their exceptional quality, precise dimensions, and long-lasting service life. Fajar Nickel Alloys caters to industries throughout Indonesia and beyond, ensuring reliable and prompt product delivery.
Super Duplex Steel S32750 Flanges are made up of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which gives them a unique dual-phase austenitic-ferritic structure. This alloy delivers impressive tensile strength (up to 800 MPa), yield strength (around 550 MPa), and outstanding resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. The flanges maintain excellent toughness and structural integrity, whether in high or low-temperature settings. Their superb weldability and fatigue strength make them perfect for high-pressure and corrosive environments.
