Yes, Super Duplex Steel Ferralium 255 Bars can be welded using suitable techniques like TIG, MIG, or SMAW, ensuring precise heat input control to prevent phase imbalance. Pre-heating and post-weld heat treatments may be required for optimal weld integrity.
Super Duplex Steel Ferralium 255 Rods are highly resistant to galvanic corrosion due to their excellent corrosion resistance properties. However, they may still experience some susceptibility in highly corrosive environments when coupled with more anodic materials.
Super Duplex Steel Ferralium 255 rods are available in a wide range of sizes, typically from 3mm to 500mm in diameter. They are offered in finishes such as hot-rolled, cold-drawn, and polished for various applications.
Super Duplex Steel Ferralium 255 Bars and Rods find extensive use in industries that demand high strength and exceptional corrosion resistance. They are particularly suited for chemical processing plants, marine engineering, desalination systems, and oil and gas equipment like pumps, valves, and heat exchangers. Additionally, they are utilized in the paper and pulp industries, power plants, and offshore platforms where exposure to chlorides and acidic conditions is frequent. Their blend of outstanding mechanical properties and corrosion resistance guarantees long-lasting performance and reliability, even in the most challenging operating environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
