The hardness of Super Duplex Steel Bright Bars typically ranges between 250-300 HB (Hardness Brinell), depending on the specific grade and heat treatment, offering excellent strength and resistance to wear and corrosion.
Yes, Super Duplex Steel Bright Bars can be recycled after use. Their high chromium and nickel content makes them highly recyclable, contributing to sustainability and reducing the need for new raw materials.
Super Duplex Steel Bright Bars are highly resistant to corrosion due to their high chromium and molybdenum content. However, in highly aggressive environments, additional coatings may be applied for extra protection.
These Super Duplex Steel Bright Bars find their way into applications that require exceptional strength, precision, and corrosion resistance. Common uses include shafts, fasteners, studs, valves, and pump components in oil and gas, offshore, and marine settings. They’re also utilized in chemical processing equipment, heat exchangers, pressure vessels, and desalination plants due to their resistance to chlorides and aggressive media. Furthermore, they are ideal for power generation, pulp and paper, and heavy engineering industries where a long service life and minimal maintenance are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
