At Sabra Metals, located in Amman, Jordan, we take pride in being a top-notch manufacturer and supplier of high-quality Super Duplex Steel square bars. Known for their remarkable strength, resistance to corrosion, and long-lasting durability, our square bars are crafted to meet the highest industrial standards. We utilize cutting-edge manufacturing techniques and maintain rigorous quality control to guarantee uniform dimensions, consistent mechanical properties, and dependable performance. Our products serve a variety of industries, including oil and gas, chemical processing, marine, and construction, providing materials that can handle even the toughest environments. With a commitment to quality and timely delivery, Sabra Metals has earned a reputation as a reliable supplier of Super Duplex Steel square bars both locally and internationally.
These square bars are made from a chromium-nickel-molybdenum alloy, featuring around 22–25% chromium, 4–6% nickel, 3–5% molybdenum, and trace amounts of nitrogen. This unique composition endows the steel with outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, along with impressive tensile strength (about 750–900 MPa) and toughness. Super Duplex Steel also offers good ductility and weldability, making it perfect for complex industrial applications that demand both mechanical performance and chemical resistance.

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.
Super Duplex Steel square bars find extensive use in oil and gas equipment, chemical processing facilities, desalination systems, marine structures, and offshore installations. They are particularly well-suited for shafts, structural supports, fasteners, and components that face highly corrosive conditions. Their blend of strength, toughness, and corrosion resistance ensures a long service life, even in extreme temperatures, exposure to seawater, and chemical attacks. Super Duplex Steel square bars are a vital material for industries that require durable, high-performance, and corrosion-resistant solutions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
