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 Icon Steel, 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.

FAQ
Super duplex refers to a group of high-performance stainless steels that contain approximately 25% chromium in their composition. Like other duplex steels, super duplex has a unique microstructure consisting of both austenitic and ferritic grains.
Our super duplex stainless steel grades, including 2507, Zeron 100, Ferralium 255, Ferrinox 255, and Grade UR52N+, are highly alloyed and possess exceptional corrosion resistance that rivals high-performance austenitic grades.
The price of super duplex stainless steel is approximately Rs 500*/Kg. Contact us to know More.
Super Duplex is a type of stainless steel alloy that contains a combination of austenitic and ferritic microstructures, along with iron, chromium, nickel, and molybdenum. This alloy exhibits strong resistance to pitting corrosion and high tensile strength, as well as superior resistance to stress corrosion cracking at moderate temperatures compared to conventional austenitic stainless steels.
