Dhruv Metals, a reputable manufacturer and supplier located in Hyderabad, India, specializes in high-performance Super Duplex Steel Bright Bars. These bars are celebrated for their remarkable strength, resistance to corrosion, and sleek polished finish. Crafted using cutting-edge cold finishing techniques, they boast impressive dimensional accuracy and a smooth surface, making them perfect for precision machining and aesthetic applications. Dhruv Metals is committed to ensuring that each bar adheres to strict quality standards and international specifications, catering to industries that require durability, reliability, and exceptional resistance to harsh environments, including offshore, marine, chemical, and engineering sectors both domestically and globally.
Super Duplex Steel Bright Bars primarily consist of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), nitrogen (0.2–0.3%), and iron, featuring a dual-phase microstructure of ferrite and austenite. This unique composition endows them with outstanding mechanical and corrosion-resistant properties. Typical mechanical characteristics include a tensile strength of around 795 MPa, yield strength exceeding 550 MPa, and an elongation of about 15%. The bright bar finish is achieved through cold drawing or centerless grinding, resulting in a precise, smooth surface that is ideal for applications demanding tight tolerances, high strength, and superior corrosion resistance.

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 find extensive use in industries that require a blend of high strength, corrosion resistance, and an excellent surface finish. In the marine and offshore sectors, they are utilized for shafts, fasteners, and structural components that are exposed to seawater and challenging environments. In the chemical and petrochemical industries, they serve in pump shafts, valves, and process equipment. Their smooth surface and dimensional accuracy make them perfect for precision components in engineering and manufacturing. Additionally, these bars are employed in desalination plants, the paper and pulp industry, and high-stress mechanical assemblies.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
