Chuck Metals is your go-to manufacturer and supplier of Super Duplex Steel Ferralium 255 Bars and Rods right here in Singapore, catering to industrial clients across Pulau Ujong and the broader Southeast Asian region. Ferralium 255 is a top-notch super duplex stainless steel celebrated for its remarkable corrosion resistance, impressive strength, and long-lasting performance even in the harshest environments. At Chuck Metals, we offer precision-machined Ferralium 255 bars and rods that adhere to strict international standards like ASTM A276 and A479. Our materials are trusted in various sectors, including chemical processing, desalination, marine, pulp and paper, and offshore oil & gas, where reliability and durability are absolutely essential.
Ferralium 255 is a super duplex alloy that boasts around 25% chromium, 5% nickel, 3.3% molybdenum, 1.7% copper, and 0.2% nitrogen. It delivers an impressive tensile strength of about 800–860 MPa, a yield strength of at least 550 MPa, and excellent impact toughness. Its corrosion resistance is superior to that of most duplex steels, showing outstanding resistance to pitting (PREN > 40), crevice corrosion, and stress corrosion cracking in environments with chlorides. The addition of copper also enhances its performance in sulfuric acid settings. Plus, Ferralium 255 is known for its good weldability and machinability, making it perfect for both corrosive and structural applications.

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 are extensively utilized in highly corrosive and mechanically demanding situations. In the chemical and petrochemical sectors, they’re essential for reactors, heat exchangers, and pressure vessels that deal with acidic and chloride-rich solutions. In marine and offshore settings, they’re used in pump shafts, seawater systems, and risers thanks to their exceptional resistance to seawater corrosion. Desalination plants, fertilizer production, pulp and paper industries, and pollution control systems all reap the benefits of Ferralium 255’s outstanding strength and corrosion resistance. Its long service life and low maintenance needs help keep lifecycle costs down.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
