Mourad Metals, located in Tunis, Tunisia, stands out as a top manufacturer and supplier of high-quality Super Duplex Steel Bars and Rods. Known for its precision engineering and unwavering commitment to excellence, the company caters to a variety of industrial sectors, including oil and gas, chemical processing, and marine engineering. Mourad Metals takes pride in producing bars and rods that adhere to strict international standards, ensuring they offer superior strength, corrosion resistance, and durability. With cutting-edge facilities and a talented workforce, the company consistently provides products that boost performance and reliability in critical applications, making it a trusted partner for clients around the globe.
Super Duplex Steel Bars and Rods are primarily made of iron, featuring about 22-25% chromium, 4-6% nickel, 3-5% molybdenum, and trace amounts of nitrogen. This distinctive composition gives them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, they boast high tensile strength (around 830–1000 MPa) and yield strength (approximately 550–700 MPa), along with good toughness and ductility. Their dual-phase microstructure, which consists of roughly equal parts austenite and ferrite, contributes to their outstanding blend of strength and corrosion resistance, making them perfect for demanding industrial settings.

Super Duplex Steel rods are generally resistant to galvanic corrosion due to their high chromium and molybdenum content. However, they can still be susceptible when coupled with highly dissimilar metals in certain environments.
Yes, Super Duplex Steel bars can be welded using appropriate techniques and filler materials. Careful control of heat input and post-weld heat treatment is essential to avoid degradation of their mechanical properties.
Super Duplex Steel rods are available in various sizes, ranging from small diameters to large rods, typically up to 300mm or more. Finishes can include hot-rolled, cold-drawn, polished, or ground, depending on the application requirements.
Super Duplex Steel Bars and Rods find extensive use in oil and gas pipelines, chemical processing equipment, heat exchangers, and marine applications. Their exceptional corrosion resistance makes them ideal for seawater systems, desalination plants, and offshore platforms. Additionally, they are utilized in pumps, valves, and fasteners that face harsh environments, as well as in structural components where strength and durability are paramount. Industries that depend on high-performance materials for safety and longevity favor Super Duplex Steel Bars and Rods because of their ability to endure tough conditions while maintaining structural integrity over long periods.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
