Sahil Metals, based in Riyadh, Saudi Arabia, is a reliable manufacturer and supplier of top-notch **Super Duplex Steel Bars and Rods**, designed for high-performance use in some of the toughest environments around the globe. Renowned for their outstanding strength and resistance to corrosion, these bars are perfect for industries like marine, offshore, chemical, and energy. Sahil Metals guarantees that each product adheres to international quality standards, providing durability, reliability, and efficiency to clients throughout Saudi Arabia and the Middle East.
Super Duplex Steel Bars and Rods are generally made with high amounts of chromium (about 25%), molybdenum (3–4%), and nitrogen, which gives them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. These bars feature a dual-phase microstructure (austenitic-ferritic) that ensures high tensile strength (usually between 750–930 MPa), excellent fatigue resistance, and good weldability. The blend of mechanical strength and corrosion protection makes them perfect for critical structural and process applications.

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.
You’ll find Super Duplex Steel Bars and Rods commonly used in offshore oil and gas platforms, desalination plants, heat exchangers, chemical processing systems, and marine settings. Their capability to endure high pressure, chloride-rich environments, and harsh chemicals makes them a dependable choice for structural components, shafts, fasteners, and pressure-containing parts. These bars help minimize maintenance needs and extend the service life of systems operating under extreme conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
