Maduka Metals, located in Abuja, Nigeria, has built a solid reputation as a top-notch manufacturer and supplier of high-quality Super Duplex Steel Round Bars. Known for their remarkable strength, resistance to corrosion, and long-lasting durability, these bars are crafted to excel in the toughest industrial settings. Maduka Metals is committed to ensuring that every product meets international quality and precision standards. The company serves a variety of industries, offering dependable Super Duplex Steel Round Bars that can handle extreme conditions, making them perfect for applications in chemical processing, marine, oil and gas, and construction throughout Nigeria and beyond.
Super Duplex Steel Round Bars feature a well-balanced microstructure of austenite and ferrite, typically made up of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen. This unique blend gives them outstanding resistance to pitting, crevice, and stress corrosion cracking. On the mechanical side, they boast high tensile strength (around 800–1000 MPa), excellent yield strength, and impressive toughness, even in low temperatures. These bars also offer great weldability and machinability, ensuring reliable performance and durability in critical engineering tasks.

Yes, Super Duplex Steel Round Bars can withstand moderately high temperatures but are not ideal for prolonged use above 300°C, as this may reduce their corrosion resistance and mechanical properties.
Yes, Super Duplex Steel Round Bars are highly recyclable. Their materials, including chromium, nickel, and molybdenum, can be reused, promoting sustainability and reducing waste in industrial applications.
No, Super Duplex Steel Round Bars typically do not require additional corrosion protection coatings, as their high chromium, molybdenum, and nitrogen content provides excellent inherent corrosion resistance in harsh environments.
These Super Duplex Steel Round Bars are widely used in industries that demand strength, corrosion resistance, and durability. They’re commonly found in offshore oil rigs, chemical processing facilities, marine environments, and desalination systems. Thanks to their excellent mechanical and anti-corrosive properties, they’re ideal for making shafts, fasteners, pump components, heat exchangers, and pressure vessels. Additionally, they play a vital role in pulp and paper processing, power generation, and architectural structures where high performance in harsh conditions is crucial. These attributes make Super Duplex Steel Round Bars essential in today’s engineering and industrial landscape.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
