George Metals, a well-known producer and supplier of premium metal products to international industries, has its headquarters in Midland, USA. Super Duplex Steel Hollow Bars are one of the company’s flagship products, and it is well-known for its accuracy and performance. These bars are designed to satisfy the demanding requirements of the petrochemical, chemical processing, oil and gas, and marine industries. George Metals guarantees that its products fulfill international standards and offer superior mechanical properties for high-performance, corrosion-resistant applications in the most demanding environments by placing a strong emphasis on quality, dependability, and prompt delivery.
The main component of Super Duplex Steel Hollow Bars is iron, which is supplemented with trace amounts of tungsten, manganese, silicon, and carbon as well as 24–26% chromium, 6–8% nickel, 3–4% molybdenum, and 0.1–0.2% nitrogen. Superior corrosion resistance is provided by this composition, particularly in environments that are high in chloride. With a tensile strength of 800–1000 MPa, a yield strength of 550–800 MPa, and an elongation of 25–40%, these bars exhibit excellent mechanical performance. They are perfect for high-pressure, high-temperature, and chemically aggressive applications because of their dual-phase microstructure (austenite and ferrite), which guarantees exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking.

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.
Industries needing exceptional mechanical strength and corrosion resistance depend on Super Duplex Steel Hollow Bars. They are utilized in subsea pipeline risers, offshore platforms, and pressure vessels subjected to extreme conditions in the oil and gas industry. They are used in reactors, pumps, and heat exchangers in the chemical processing industry where resistance to aggressive media is essential. These bars are also used in petrochemical facilities, desalination plants, and marine engineering, especially in areas where pitting and crevice corrosion are issues. They are perfect for structural and mechanical components in demanding industrial systems because of their resilience to high temperatures and pressures.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
