Nestled in the heart of Kinshasa, Sadiki Metals stands as a trusted partner for industry, bringing unparalleled expertise in high-performance materials to the Congo. We take pride in manufacturing and supplying robust Super Duplex Steel bars and rods, engineered to meet the most rigorous demands. Our commitment is to provide local and regional projects with reliable, top-tier materials that ensure longevity and safety, supporting the growth and resilience of the infrastructure and industries that drive our community forward.
The exceptional strength of Super Duplex Steel comes from its sophisticated composition, which includes high levels of chromium, nickel, molybdenum, and nitrogen. This unique blend gives these bars and rods an extraordinary yield strength, nearly double that of standard stainless steels. They also possess outstanding toughness and excellent resistance to stress corrosion cracking, making them incredibly durable under immense pressure and in challenging environments where other materials would fail.

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 our Super Duplex Steel bars and rods hard at work in some of the most demanding settings imaginable. They are essential in the offshore oil and gas industry for critical components like subsea pipelines and wellhead equipment, where saltwater corrosion is a constant threat. They are also vital in chemical processing plants, desalination units, and for structural elements in bridges and buildings located in highly corrosive coastal areas, ensuring integrity and safety for decades.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Sadiki Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Kinshasa, Congo
