Ojas Pipes and Tubes, a well-respected manufacturer and supplier located in Kolkata, India, specializes in crafting high-performance Super Duplex Steel Bright Bars tailored for critical industrial applications. These bars are celebrated for their remarkable strength, resistance to corrosion, and precise dimensional tolerances, all achieved through advanced manufacturing processes and top-notch raw materials. The bright finish not only enhances their look but also boosts functionality, making them perfect for demanding environments. Ojas Pipes and Tubes is dedicated to providing reliable and consistent products across various sectors, including oil & gas, marine, and chemical industries, with a strong emphasis on quality assurance, timely delivery, and customer satisfaction
Super Duplex Steel Bright Bars are made up of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.2–0.3% nitrogen, which gives them outstanding corrosion resistance. Their unique dual-phase microstructure ensures superior strength and toughness. Typical mechanical properties include a tensile strength ranging from 750–1000 MPa, a yield strength of about 550 MPa, and excellent fatigue resistance. These bars also boast high resistance to pitting, crevice corrosion, and stress corrosion cracking, making them perfect for extreme environments. The bright finish enhances their surface smoothness and visual appeal, which is particularly advantageous in high-spec installations.

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 offshore oil and gas platforms, desalination plants, marine engineering, and chemical processing equipment, thanks to their high strength and exceptional corrosion resistance. They are also perfect for heat exchangers, valves, pumps, and pressure vessels that operate in harsh environments. Their bright finish makes them ideal for precision machining, automotive components, and architectural applications where both performance and aesthetics are crucial. In industries that demand high resistance to chloride-rich conditions, these bars truly shine, proving their worth in challenging settings.
