Located in the heart of Manama, Bahrain, Junaid Metals has built a strong reputation for providing exceptional materials to demanding industries. We take pride in our supply of Super Duplex Steel Hollow Bars, a product engineered for extreme conditions. These bars represent the pinnacle of corrosion resistance and mechanical strength, offering a reliable and long-lasting solution for projects where failure is not an option, from the depths of the sea to the heart of chemical processing plants.
The exceptional performance of this steel comes from its sophisticated composition, which includes high levels of chromium, nickel, molybdenum, and nitrogen. This unique blend gives the hollow bar outstanding resistance to pitting and chloride stress corrosion cracking. Mechanically, it is remarkably strong, offering roughly double the yield strength of standard austenitic stainless steels, combined with good toughness and ductility, making it suitable for heavy-load applications.

Yes, Super Duplex Steel Hollow Bars can withstand high temperatures due to their excellent strength and corrosion resistance. They are suitable for applications in environments up to around 300°C (572°F), depending on the specific alloy.
Super Duplex Steel Hollow Bars and Rods are manufactured through hot or cold working processes, including extrusion and forging, followed by heat treatment, cold drawing, and precision machining for enhanced strength and corrosion resistance.
Super Duplex Steel Hollow Bars have excellent natural corrosion resistance due to their high chromium and molybdenum content, making additional protective coatings generally unnecessary. However, in highly aggressive environments, coatings may offer extra protection.
This impressive combination of properties makes the Super Duplex Steel Hollow Bar indispensable in several critical sectors. It is widely used for constructing subsea oil and gas components, such as pump shafts and connectors, where saltwater resistance is paramount. The chemical processing industry relies on it for agitators, heat exchanger tubes, and piping systems that handle highly corrosive substances. It’s also a preferred material for desalination plant equipment and in the construction of large-scale architectural marine structures.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
