Nestled in the industrial heart of Safat, Kuwait, Nimish Metal has built a strong reputation for providing top-tier materials to a demanding market. We take particular pride in our range of Super Duplex Steel Hollow Bars, a product engineered for resilience. These bars are the go-to choice for industries facing extreme conditions, where failure is not an option. Our commitment is to supply not just metal, but a reliable foundation for your most critical projects, backed by local expertise and a dedication to enduring quality.
The exceptional strength of our Super Duplex Steel Hollow Bar comes from its unique composition, which includes a high content of chromium, nickel, molybdenum, and nitrogen. This powerful blend gives the material an outstanding resistance to pitting and corrosion, especially in chloride-rich environments. Mechanically, it offers a remarkable yield strength that is about double that of standard austenitic stainless steels, combined with excellent toughness. This means you get a product that is both incredibly strong and highly resistant to the harsh elements that can degrade lesser materials.

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.
Our Super Duplex Steel Hollow Bars are ideally suited for challenging applications where both strength and corrosion resistance are paramount. They are extensively used in the offshore oil and gas industry for critical components like pumps, valves, and fasteners that must withstand aggressive seawater. The chemical processing and desalination sectors also rely on them for heat exchangers and piping systems. Furthermore, their superior performance makes them a smart choice for construction in marine environments, ensuring the longevity and safety of structural elements exposed to salt and pressure.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
