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.
Super Duplex Steel Hex Bars find extensive use in the oil and gas, chemical processing, marine, desalination, and power generation sectors. They are perfect for creating fasteners, bolts, shafts, flanges, and other components that come into contact with aggressive chemicals and seawater. Their exceptional durability reduces maintenance needs, minimizes downtime, and guarantees a long service life. Semih Metals’ Super Duplex Steel Hex Bars offer robust, corrosion-resistant, and high-performance solutions for industries that demand strong and dependable materials in challenging operational conditions.
