From the vibrant industrial hub of Addis Ababa, Tariku Metals is proud to supply Ethiopian industry with the exceptional quality of Super Duplex Steel Square Bars. We understand the demands of challenging environments, which is why we provide this premium material known for its incredible resilience and long-lasting performance. When your project requires a bar stock that can truly withstand the test, you can rely on our consistent supply and deep understanding of advanced metallurgy to support your most ambitious engineering and construction goals.
The remarkable strength of Super Duplex Steel comes from its carefully balanced composition, which boasts high levels of chromium, nickel, molybdenum, and nitrogen. This specific blend gives the square bars an outstanding resistance to pitting and corrosion, far surpassing standard stainless steels. Mechanically, they offer an impressive yield strength, often double that of austenitic grades, combined with excellent toughness. This means components made from our bars are not only incredibly durable but can also be designed with thinner sections, optimizing both weight and material efficiency.

To maintain Super Duplex Steel Square Bars, clean them regularly to remove contaminants, avoid exposure to extreme temperatures for prolonged periods, and inspect for signs of corrosion or damage in harsh environments.
Yes, Super Duplex Steel Square Bars can be welded using techniques like TIG or MIG welding. Proper preheating and post-weld heat treatment are essential to maintain their corrosion resistance and mechanical properties.
Yes, Super Duplex Steel Square Bars are suitable for natural gas applications due to their excellent resistance to corrosion, high strength, and ability to withstand harsh environments commonly found in the natural gas industry.
These properties make our Super Duplex Steel Square Bars ideal for a wide range of demanding applications. You’ll find them essential in offshore and marine equipment, chemical processing plants, and pollution control systems where saltwater or aggressive chemicals are present. They are also perfectly suited for the construction of bridges, hydraulic systems, and components in the oil and gas industry. Essentially, any project that faces harsh, corrosive environments will benefit from the superior longevity and reliability that this advanced material provides, ensuring structural integrity for years to come.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
