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 **Super Duplex Steel Bars and Rods** widely utilized in industries that demand high strength and corrosion resistance. They’re perfect for offshore platforms, marine hardware, chemical and petrochemical processing equipment, heat exchangers, and pressure vessels. In the oil and gas sector, they’re employed in pipelines, valves, pumps, and risers that come into contact with seawater or harsh chemicals. Their impressive strength-to-weight ratio and durability also make them ideal for structural components in power generation, desalination systems, and various other industrial applications where reliability and long-term performance are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
