Latham Steel, located in Hamilton, New Zealand, stands out as a top-notch manufacturer and supplier of Super Duplex Steel Ferralium 255 Bars and Rods. Their products are designed with a focus on strength, durability, and resistance to corrosion. Ferralium 255 uniquely blends austenitic and ferritic microstructures, which allows it to perform exceptionally well in tough environments. Thanks to rigorous quality control and cutting-edge manufacturing techniques, Latham Steel guarantees that every bar and rod adheres to international standards. These materials are highly regarded in industries that demand high-performance solutions, providing reliable and long-lasting options for engineering, offshore, and chemical processing applications.
Super Duplex Steel Ferralium 255 consists of about 25% chromium, 7% nickel, 4% molybdenum, and 0.24% nitrogen, along with trace amounts of copper and tungsten to boost its corrosion resistance and strength. This alloy is known for its remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in environments rich in chlorides and acids. On the mechanical side, Ferralium 255 bars and rods boast impressive tensile strength, ranging from 900 to 1000 MPa, and excellent yield strength, around 650 to 700 MPa, while also maintaining good toughness at lower temperatures. These characteristics make it a perfect choice for applications that require both durability and reliability in extreme 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.
Super Duplex Steel Ferralium 255 Bars and Rods find extensive use in offshore oil and gas platforms, marine engineering, chemical processing facilities, desalination systems, and the pulp and paper industry. They are particularly well-suited for crafting shafts, flanges, pipelines, valves, and pressure vessels that face harsh conditions. With their high strength-to-weight ratio, outstanding corrosion resistance, and ability to endure thermal and mechanical stress, Ferralium 255 is the go-to material for critical components that need to last long, require minimal maintenance, and operate safely in demanding environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
