Super Duplex Steel Ferralium 255 Fasteners

Super Duplex Steel Ferralium 255 Fasteners About

Super Duplex Steel Ferralium 255 Fasteners are becoming increasingly popular in various industries thanks to their high strength and superior corrosion resistance. But what precisely gives these fasteners their unique properties? The answer lies in their chemical composition, which includes a blend of chromium, molybdenum, nitrogen, and nickel. Adding these elements provides Ferralium 255 Fasteners with excellent corrosion resistance and remarkable resistance to pitting and crevice corrosion.

Engineered for Extreme Environments

Ferralium 255 fasteners are crafted to withstand the harshest conditions, including aggressive marine, offshore, and chemical processing settings. Their superior corrosion resistance and impact toughness make them ideal for applications where standard stainless steels fail. The solution-annealed duplex structure ensures longevity and consistent performance, even under fluctuating temperatures and corrosive agents.


Versatile Customization and Compliance

These fasteners are available in a wide variety of forms, including hex bolts, socket caps, studs, nuts, and washers. They meet globally recognized standards such as ASTM A182, A479, and A276, and can be tailored in size, shape, thread type, and coating according to project specifications. This level of versatility makes them suitable for both standard and specialty requirements in diverse industrial applications.


Reliable Performance in Demanding Applications

With a minimum yield strength of 570 MPa and tensile strength above 800 MPa, Super Duplex Steel Ferralium 255 fasteners offer robust mechanical support. Their moderate machinability allows for precise fabrication, while their excellent resistance to pitting, crevice corrosion, and stress corrosion cracking ensures safety and reliability in seawater, chloride, and sulphide-rich environments.
