Sabra Metals stands out as a top manufacturer and supplier based in Amman, Jordan, focusing on high-quality Super Duplex Steel Hollow Bars. These bars are perfect for industries that require exceptional strength, corrosion resistance, and durability. The company is well-regarded for its precision engineering and commitment to international standards, ensuring that their steel products perform reliably even in the toughest and most corrosive environments. Super Duplex Steel Hollow Bars are known for their remarkable mechanical properties and their ability to resist stress corrosion cracking, pitting, and crevice corrosion. With cutting-edge production capabilities and strict quality control measures, Sabra Metals delivers trusted solutions for sectors like oil and gas, chemical processing, marine, and petrochemicals.
These Super Duplex Steel Hollow Bars are crafted from a well-balanced mix of austenitic and ferritic stainless steel, which gives them high tensile strength and impressive toughness. Typically, they contain 22–25% chromium, 5–7% nickel, 3–5% molybdenum, and trace amounts of nitrogen, all of which boost their corrosion resistance in harsh, chloride-rich environments. They also excel in dimensional stability, fatigue resistance, and weldability. Thanks to their duplex microstructure, these bars offer a fantastic blend of mechanical strength and corrosion performance, making them a superior choice compared to standard austenitic or ferritic stainless steels for demanding 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.
Super Duplex Steel Hollow Bars find their place in various industries where mechanical strength and corrosion resistance are paramount. They’re commonly used in oil and gas pipelines, chemical processing equipment, pressure vessels, and heat exchangers. Their ability to withstand chloride-induced stress corrosion cracking makes them particularly suitable for marine environments and offshore structures. Additionally, these bars are utilized in petrochemical plants, desalination facilities, and the pulp and paper industry, ensuring reliable performance even under high-pressure, high-temperature, and corrosive conditions. Their hollow design adds to their versatility and effectiveness in these challenging applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
