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 this hex bar is indispensable for demanding applications, particularly in coastal projects and chemical processing plants around Ethiopia. It’s perfectly suited for manufacturing high-strength fasteners, robust pump shafts, and essential valve components. Its proven durability in aggressive environments makes it a smart choice for infrastructure that must withstand corrosion, pressure, and wear, ensuring long-term performance and safety.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Tariku Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Addis Ababa, Ethiopia
