Maduka Metals, a top-notch manufacturer and supplier located in Abuja, Nigeria, specializes in high-quality Super Duplex Steel Bright Bars. These bars are designed for outstanding strength, corrosion resistance, and durability. Crafted to meet international standards, they ensure precise dimensions and reliable performance, even in the toughest industrial and marine settings. Maduka Metals caters to a range of industries, including oil and gas, chemical processing, petrochemical, and power generation, offering cutting-edge steel solutions. Thanks to advanced manufacturing techniques and rigorous quality control, each Super Duplex Steel Bright Bar boasts excellent mechanical properties, long-lasting stability, and resistance to pitting, stress corrosion, and chloride-induced cracking, making them perfect for critical applications.
These Super Duplex Steel Bright Bars contain about 22–25% chromium, 5–7% nickel, 3–5% molybdenum, along with trace amounts of nitrogen, manganese, and iron. This well-balanced composition results in high tensile and yield strength, remarkable toughness, and exceptional corrosion resistance, including protection against pitting and stress corrosion cracking. On the mechanical side, these bright bars show a tensile strength ranging from 800 to 1000 MPa, yield strength between 550 and 750 MPa, and hardness up to 350 HB. The blend of mechanical strength and corrosion resistance guarantees dependable performance in harsh chemical, marine, and industrial environments.

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 extensively utilized in industries that demand corrosion-resistant, high-strength materials with precise dimensional accuracy. In the oil and gas sector, they are used for valves, shafts, fasteners, and other essential components that come into contact with chloride-rich environments. The chemical and petrochemical industries rely on them for pumps, heat exchangers, and piping systems that handle aggressive chemicals. In marine applications, these bright bars are perfect for offshore structures, shipbuilding, and desalination plants. Moreover, Super Duplex Steel Bright Bars are also well-suited for power generation applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
