In the heart of Manama’s industrial landscape, Junaid Metals has established itself as a trusted source for high-performance materials. We take pride in supplying industry professionals with exceptional Super Duplex Steel Ferralium 255 bars and rods. This material is specifically chosen for the most demanding environments, offering a superior combination of resilience and longevity that stands up to extreme challenges, making it an ideal choice for critical projects where failure is not an option.
The strength of Ferralium 255 lies in its carefully balanced composition of chromium, nickel, molybdenum, and a notable addition of copper. This unique mix grants it outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, it is remarkably robust, offering nearly double the yield strength of standard stainless steels, alongside excellent toughness and ductility, which allows it to perform reliably under high stress and in punishing conditions.

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.
This impressive set of properties makes Ferralium 255 bars and rods invaluable across several heavy-duty sectors. They are extensively used in offshore oil and gas platforms, desalination plants, and chemical processing equipment where exposure to aggressive chlorides is a constant concern. You will also find these components in marine engineering, power generation, and pollution control systems, effectively handling everything from seawater pumps and heat exchangers to critical structural elements that demand unwavering integrity over the long term.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
