Yes, Super Duplex Steel S32760 bars can be welded. However, it requires careful control of heat input and post-weld heat treatment to maintain its corrosion resistance and mechanical properties.
Super Duplex Steel S32760 rods are available in a wide range of sizes, typically from 6mm to 300mm in diameter. They can be supplied in various finishes, including hot-rolled, cold-drawn, and polished finishes.
Super Duplex Steel S32760 rods are highly resistant to galvanic corrosion due to their excellent corrosion resistance properties. However, if exposed to highly aggressive environments, the risk may increase when coupled with more anodic metals.
Super Duplex Steel S32760 Bars and Rods find extensive use in industries that require high performance and corrosion resistance. They are perfect for offshore platforms, subsea pipelines, heat exchangers, pressure vessels, and desalination plants. In the chemical and petrochemical sectors, these materials are utilized in processing equipment that faces acidic and chloride-rich conditions. Additionally, the marine and shipbuilding industries rely on these bars and rods for structural and mechanical components that need to withstand the harshness of seawater corrosion. Their robust characteristics make them a top choice for heavy-duty engineering projects.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
