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 across various industries, including oil and gas, marine, petrochemical, power generation, and desalination. They’re ideal for crafting shafts, fasteners, pump components, heat exchangers, and structural parts that face seawater and corrosive chemicals. On offshore platforms, they deliver reliable performance in highly saline conditions, while in chemical plants, they stand strong against aggressive acids and alkalis. Their excellent strength-to-weight ratio and extended service life make them a smart, cost-effective choice for projects that demand durability, safety, and low maintenance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
