With a focus on quality, we provide timely delivery and accurate specifications to all our clients for maximum reliability and performance.
Super Duplex Steel is an alloy used to combine the best characteristics of both austenitic and ferritic stainless steels. Generally consisting of approximately 25% chromium, 7% nickel, and 3-5% molybdenum, with minor amounts of nitrogen, this alloy provides superior resistance to pitting, crevice, and stress corrosion cracking. It also offers high tensile strength (up to 100 ksi), good impact toughness, and a hardness of about 250-300 HB. Super Duplex Steel has better resistance to localized and general corrosion in chloride environments, thus being well suited to be used in marine, chemical, and offshore applications.

Super Duplex Steel rods are generally resistant to galvanic corrosion due to their high chromium and molybdenum content. However, they can still be susceptible when coupled with highly dissimilar metals in certain environments.
Yes, Super Duplex Steel bars can be welded using appropriate techniques and filler materials. Careful control of heat input and post-weld heat treatment is essential to avoid degradation of their mechanical properties.
Super Duplex Steel rods are available in various sizes, ranging from small diameters to large rods, typically up to 300mm or more. Finishes can include hot-rolled, cold-drawn, polished, or ground, depending on the application requirements.
Super Duplex Steel Bars and Rods are very versatile and find extensive application in numerous types of applications in different industries. These include pressure vessels, heat exchangers, pipelines, subsea equipment, and valves in the oil and gas industry. Super Duplex Steel is applied in marine applications to offshore platforms and desalination plants. The resistance of the alloy to corrosive media like chemicals, acids, and seawater also qualifies it for use in chemical and food processing industries. These rods and bars are particularly beneficial in conditions that require high strength and resistance to corrosion, which maintains durability for a long period.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
