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.
Super Duplex Steel Hollow Bars find their place in various industries that require top-notch corrosion resistance and mechanical performance. They’re frequently used in chemical processing, oil and gas, marine engineering, desalination plants, and the pulp and paper sector. These hollow bars are perfect for components like shafts, flanges, valves, and pipelines that face harsh conditions. Their ability to resist chloride-induced corrosion and their impressive strength-to-weight ratio make them ideal for subsea equipment, heat exchangers, and pressure vessels. Engineers count on Super Duplex Steel Hollow Bars for long-lasting, low-maintenance solutions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
