The strength of Super Duplex Steel lies in its carefully balanced composition, which includes high levels of chromium, nickel, molybdenum, and nitrogen. This specific blend creates a material with exceptional mechanical properties, offering a remarkable combination of high tensile strength and outstanding toughness. It possesses excellent resistance to stress corrosion cracking, a common failure point in harsh environments. Essentially, these bars and rods are engineered to withstand immense pressure and resist wear far beyond the capabilities of standard stainless steels.

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.
You’ll find our Super Duplex Steel Bars and Rods performing critical roles in some of the world’s most demanding environments. They are essential in offshore oil and gas platforms, resisting the corrosive power of seawater. The chemical processing industry relies on them for equipment that handles aggressive acids, while desalination plants use them for components that must endure highly saline conditions. From shafts and pumps to valves and fasteners in marine engineering, these materials are chosen where failure is not an option, ensuring safety, longevity, and operational integrity.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
