Super Duplex Steel Ferralium 255 Bars and Rods are prized for their remarkable blend of high strength, exceptional corrosion resistance, and impressive durability, especially in tough industrial and marine settings. Crafted with precision, these bars and rods offer outstanding mechanical stability, toughness, and reliability. Their ability to resist pitting, crevice corrosion, and stress corrosion cracking makes them perfect for critical applications where both structural integrity and performance are key. You’ll find Ferralium 255 Bars and Rods commonly used in the chemical, petrochemical, offshore, and marine industries, where demanding operations call for top-notch material performance.
These bars and rods are made from a high-alloy stainless steel that contains around 25–26% chromium, 6–7% nickel, and 4–5% molybdenum, along with trace amounts of nitrogen and other elements. This unique composition gives them excellent resistance to corrosion caused by chlorides and acidic environments, while also providing superior mechanical properties. In terms of mechanics, these bars and rods boast high tensile and yield strength, impressive toughness, and good ductility. Their combination of corrosion resistance and mechanical performance guarantees reliable and durable operation even under high pressure, elevated temperatures, and chemically aggressive conditions.
