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.
These Super Duplex Steel Hex Bars find extensive use in offshore, oil and gas, chemical processing, desalination, and marine industries. They are commonly used in fasteners, bolts, shafts, pump and valve components, structural parts, and pressure vessels that are exposed to corrosive environments. Their exceptional mechanical strength and corrosion resistance make them ideal for high-stress applications where reliability, longevity, and safety are paramount. Super Duplex Steel Hex Bars offer extended service life and peace of mind in demanding conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
