Yes, Super Duplex Steel Hex Bars are magnetic due to their mixed microstructure of austenite and ferrite, which gives them magnetic properties, though they are less magnetic than ferritic steels.
Yes, Super Duplex Steel Hex Bars are suitable for hygienic and sanitary applications due to their corrosion resistance, durability, and ease of cleaning, making them ideal for industries like food processing and pharmaceuticals.
Super Duplex Steel Hex Bars are less susceptible to galvanic corrosion compared to other materials due to their high corrosion resistance. However, they may still experience galvanic corrosion when in contact with less resistant metals.
You’ll find the Super Duplex Steel Hex Bar widely utilized in industries that demand high strength and corrosion resistance. It’s commonly used in offshore oil and gas platforms, chemical processing facilities, marine engineering, heat exchangers, and the pulp and paper sector. Thanks to its remarkable mechanical and corrosion-resistant qualities, it’s perfect for components like shafts, fasteners, valves, and pumps that face harsh environments. The hexagonal shape of the bar makes it easy to machine and fit precisely into mechanical assemblies. Built to endure extreme conditions, it guarantees lasting performance and reliability across a range of industrial and structural applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
