Super Duplex Steel Ferralium 255 Nuts About

The Super Duplex Steel Ferralium 255 Nuts stand out as a remarkable innovation in the world of metallurgy with their unique chemical composition and impressive properties. These specialized nuts comprise a perfectly balanced mix of chromium, molybdenum, copper, nickel, and nitrogen, which account for their remarkable strength, durability, and resistance to harsh conditions. The combined presence of these essential elements enhances the material's strength and toughness and provides exceptional resistance to stress corrosion, pitting, and crevice corrosion.

Exceptional Strength and Corrosion Resistance

Ferralium 255 Nuts are manufactured for use in highly corrosive environments and offer notable resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. With a high tensile strength of at least 800 MPa and robust impact performance at low temperatures, these nuts provide reassuring reliability for structural and mechanical applications where durability and safety are paramount.

Tailored for Diverse Applications

These nuts can be supplied in various diameters (M6 to M64 or custom), thread types (metric/imperial, coarse/fine), and finishes (bright, passivated, etc.). Engineered for a wide range of industries-from marine and desalination plants to chemical processing and power generation-they combine excellent performance with adaptability, meeting international standards such as ASTM A479/A182 and ASME SA479/SA182.

Manufacturing and Customization Options

Utilizing both cold and hot forging techniques followed by precision machining, Ferralium 255 nuts deliver consistent quality and dimensional accuracy. Clients can specify thread type, dimension, temper, and surface finish, as well as packaging requirements-jute bags, wooden boxes, or custom packaging-ensuring seamless integration into any project specification or engineering drawing.
