A Super Duplex Steel Round Bar is a high-performance metal product. Known for its dual-phase microstructure. Combining nearly equal proportions of austenite and ferrite. This composition offers superior mechanical strength & exceptional corrosion resistance. Typically Super Duplex Steel contains 24-26% Chromium, 6-8% Nickel, 3-4% Molybdenum, 0.2-0.3% Nitrogen. And small amounts of manganese and silicon along with balanced iron. It exhibits excellent resistance to pitting, crevice corrosion and stress corrosion cracking. Making it suitable for harsh environments like marine, chemical, and oil and gas industries. Its high tensile strength, durability and low thermal expansion make it a preferred choice for critical applications.

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.
Super Duplex Steel Round Bars are widely used in industries requiring high strength and superior corrosion resistance. Their excellent mechanical properties and ability to withstand harsh environments make them ideal for applications in the marine industry, including shipbuilding, offshore platforms, and desalination plants. In the oil and gas sector they are employed in heat exchangers, pipelines and pressure vessels. The chemical processing industry utilizes them for reactors, tanks and fittings. Due to their resistance to aggressive chemicals. Additionally, they are used in power plants and pulp and paper industries. Their durability and reliability make them indispensable in demanding industrial environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
