Sadiki Metals, a prominent manufacturer and supplier located in Kinshasa, Congo, specializes in top-notch Super Duplex Steel Bright Bars that are crafted for outstanding strength, precision, and durability. With cutting-edge production facilities and a commitment to global quality standards, Sadiki Metals guarantees that each bright bar performs exceptionally well in even the most demanding applications. Renowned for their superb finish, precise dimensions, and impressive corrosion resistance, these Super Duplex Steel Bright Bars are perfect for industries like oil and gas, petrochemical, marine, and power generation. Their blend of toughness, wear resistance, and extended service life makes them a dependable choice for essential engineering projects.
Super Duplex Steel Bright Bars are made up of a blend of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, which together create a unique dual-phase microstructure of ferrite and austenite. This special mix gives them impressive mechanical strength and excellent resistance to corrosion. These bars typically have a tensile strength ranging from 800 to 1000 MPa and a yield strength of about 550 MPa, along with remarkable hardness and fatigue resistance. Their outstanding toughness and stability in extreme pressure and temperature conditions make them perfect for tough environments. Plus, the bright finish not only looks great but also ensures a smooth surface quality, enhancing machinability for precision engineering tasks.

The hardness of Super Duplex Steel Bright Bars typically ranges between 250-300 HB (Hardness Brinell), depending on the specific grade and heat treatment, offering excellent strength and resistance to wear and corrosion.
Yes, Super Duplex Steel Bright Bars can be recycled after use. Their high chromium and nickel content makes them highly recyclable, contributing to sustainability and reducing the need for new raw materials.
Super Duplex Steel Bright Bars are highly resistant to corrosion due to their high chromium and molybdenum content. However, in highly aggressive environments, additional coatings may be applied for extra protection.
Super Duplex Steel Bright Bars are a go-to choice in various industries where you need high strength, resistance to corrosion, and a nice finish. You’ll find them in pump shafts, fasteners, marine components, heat exchangers, and equipment used in oil refineries and chemical plants. Their shiny, polished surface makes them perfect for situations where both function and looks matter, like in architectural designs and precision instruments. In marine and offshore applications, they stand out for their remarkable resistance to pitting and crevice corrosion. Plus, they’re also used in the paper, power, and food processing sectors, delivering dependable performance even in tough, corrosive environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
