Duplex Steel S32205 Coils are primarily made up of a balanced microstructure, featuring about 50% austenite and 50% ferrite, which allows them to harness the best qualities of both phases. This steel includes roughly 22% chromium, 5–6% nickel, 3% molybdenum, and trace amounts of nitrogen, all of which boost its corrosion resistance and mechanical properties. It showcases high tensile strength, excellent toughness, and superior resistance to stress corrosion cracking, making it perfect for challenging environments. With a yield strength that’s nearly double that of standard austenitic stainless steels, S32205 coils are ideal for applications that demand both strength and durability.

These coils find extensive use in the chemical processing, petrochemical, oil and gas, and marine industries, thanks to their exceptional resistance to pitting, crevice, and stress corrosion. They are perfect for heat exchangers, pressure vessels, storage tanks, pipelines, and structural components that face aggressive conditions. The combination of high strength and corrosion resistance also makes them a great fit for seawater desalination plants, offshore platforms, and pulp and paper processing equipment. Engineers and fabricators often choose S32205 coils for projects where both mechanical performance and longevity are crucial.
