Maduka Metals, a reputable manufacturer and supplier located in Abuja, Nigeria, specializes in providing top-notch **Super Duplex Steel Rectangular Bars** that are built to meet the rigorous standards of various industries. Renowned for their exceptional strength, resistance to corrosion, and long-lasting durability, these bars are perfect for challenging environments. At Maduka Metals, every product is meticulously crafted to ensure precision and consistency, delivering outstanding mechanical performance and reliability. With a strong commitment to excellence, the company caters to a diverse array of industries, including oil and gas, chemical processing, and marine engineering, offering tailored Super Duplex Steel Rectangular Bars that comply with both national and international standards.
Super Duplex Steel Rectangular Bars are mainly made up of chromium (about 25%), nickel (7%), molybdenum (4%), and nitrogen, which provide remarkable resistance to pitting, crevice, and stress corrosion. These bars boast a high tensile strength of roughly 800–850 MPa and a yield strength of around 550 MPa, along with impressive toughness and hardness. The well-balanced microstructure of austenite and ferrite enhances their durability, weldability, and performance in high-pressure and high-temperature settings, ensuring they remain reliable and stable over time.

When selecting Super Duplex Steel Rectangular Bars, consider factors like corrosion resistance, mechanical strength, operating temperature, application environment, and compliance with industry standards for optimal performance.
Yes, Super Duplex Steel Rectangular Bars can be welded using appropriate techniques such as TIG or MIG welding. However, proper heat control is necessary to maintain their corrosion resistance and mechanical properties.
Super Duplex Steel Rectangular Bars are not ideal for cryogenic applications, as their toughness and ductility may decrease at extremely low temperatures, potentially leading to brittleness in such environments.
Super Duplex Steel Rectangular Bars find extensive use in industries that require both strength and corrosion resistance in extreme conditions. They are particularly suited for offshore oil drilling equipment, chemical processing facilities, desalination systems, heat exchangers, and marine applications. Additionally, these bars are employed in structural frameworks, pressure vessels, and the pulp and paper industry, where exposure to corrosive chemicals and seawater is prevalent. Their outstanding mechanical properties and excellent weldability make them ideal for both fabrication and maintenance tasks in industrial, commercial, and infrastructure projects.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
