Super Duplex Stainless Steel Manufacturer

Super Duplex Stainless Steel is a highly durable and corrosion-resistant alloy that offers excellent strength, ductility, and toughness. It is a combination of austenitic and ferritic stainless steels, making it ideal for applications that require high strength and resistance to corrosion in harsh environments.

The outstanding mechanical and corrosion-resistant properties of Super Duplex Stainless Steel make it an ideal choice for applications that require superior performance under extreme conditions. It exhibits excellent resistance to corrosion, pitting, and crevice corrosion in acidic and chloride environments. Super Duplex Stainless Steel also offers high resistance to stress corrosion cracking, erosion, and fatigue.

At Omsteel, we offer a wide range of Super Duplex Stainless Steel grades, including SAF 2507, SAF 32750, and SAF 32760. Our materials meet international standards and are available in various forms such as sheets, plates, bars, and pipes. We can also provide customized solutions based on your specific requirements.
