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 are used in a variety of applications requiring excellent corrosion resistance, high strength and excellent resistance to stress forming corrosion cracking Commonly used in medical, marine applications environment, offshore oil and gas platforms , and occurs in power plants, especially at high temperatures, In applications in conditions where are as hard as salt water and in strong chemicals, these are also used in bars and rods in equipment such as heat exchangers, pressure vessels, tanks and piping systems. The superior mechanical properties and durability make Ferralium 255 ideal for complex applications where long-term performance is essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
