Super Duplex Fasteners are made from a unique blend of ferrite and austenite and are designed for applications that demand high corrosion resistance and strength. Super Duplex Fasteners contain molybdenum, nitrogen, and chromium, which protect against crevice corrosion and chloride pitting. Super Duplex Fasteners are ideal for harsh environments like warm chlorinated water and chloride-rich media, offering strong resistance to erosion, abrasion, and both uniform and localized corrosion at high temperatures. Commonly used in marine and offshore settings, Super Duplex Fasteners feature low thermal expansion, excellent fatigue resistance, high mechanical strength, and good weldability.
Explore our extensive range of Super Duplex Steel Products, including pipes, tubes, flanges, and fittings, all known for their outstanding corrosion resistance and durability in challenging environments.
Super Duplex 2507 bolts, in particular, are designed to handle high pressure and temperature, making them ideal for demanding environments. Super Duplex Fasteners enhanced corrosion resistance makes them suitable for applications involving seawater or corrosive substances. These bolts are well-suited for offshore and oilfield operations, combining strength, durability, and corrosion resistance for reliable performance in tough conditions. Super Duplex 1.4410 fasteners are gaining popularity due to their exceptional strength and superior corrosion resistance. Available in a range of types like screws, bolts, nuts, washers, rivets, and anchors, Super Duplex Fasteners offer high fatigue strength and excellent resistance to hot corrosion
