Duplex Steel S32205 Flanges

The duplex stainless steel alloy used to make UNS S31803 flanges is renowned for its exceptional strength and resistance to corrosion. They are reliable in high-pressure systems as they are stronger than many austenitic grades and perform well in environments exposed to stress corrosion cracking. These flanges are appropriate for temperatures ranging from -50°F to 1200°F and come in blind, slip-on and weld neck designs. They also have good weldability. With a composition of 0.3% molybdenum, 7% manganese, 4.5% nickel and 25% chromium the alloy has exceptional durability. Metracore Alloys Private Limited is a trusted manufacturer that manufactures Duplex Steel S31803 Flanges that meet stringent mechanical and chemical specifications to provide enduring performance in demanding applications.

These flanges come in sizes ranging from ½” to 48″, with custom dimensions available, and are manufactured in accordance with ASTM A182 / ASME SA182 standards. Compared to many stainless steels, duplex 2205 flanges are stronger and more durable, and their dual-phase structure offers exceptional resistance to corrosion cracking caused by chloride stress. Additionally, they are also easily welded which enables installation. Excellent impact strength, low thermal expansion, high thermal conductivity and superior resistance to pitting and crevice corrosion are some of its key characteristics. This balance of properties makes S32205 duplex stainless steel flanges dependable for demanding use in tough environments.

SA 182 F60 flanges and ASTM A182 F60 flanges are widely used in industries where safety and reliability are vital. Common applications include offshore oil and gas systems, chemical processing plants, desalination units, power plants, pulp and paper industries and water treatment facilities. Their resistance to aggressive chloride-rich environments makes them perfect for seawater service. The manufacturing process includes forging or rolling, solution annealing, precise machining, bolt hole drilling, and rigorous testing. This careful process ensures each flange delivers the required dual-phase microstructure and excellent corrosion performance.
