High-end Super Duplex Steel Bright Bars from Neil Metals, a well-known producer and supplier in Kolkata, India, are prized for their remarkable strength, finish, and corrosion resistance. Our bright bars are produced with precise dimensional accuracy and a superior surface finish through the use of sophisticated processes and rigorous quality checks. These bars are perfect for uses where performance and appearance are important considerations. Neil Metals provides a broad range of sizes and specifications to industries such as power generation, chemical processing, oil and gas, and marine. We are dedicated to providing dependable, high-performing materials along with prompt customer service and solutions.
The typical composition of Super Duplex Steel Bright Bars is 3–5% molybdenum, 6–8% nickel, 24–26% chromium, and trace amounts of manganese and nitrogen. A special combination of exceptional corrosion resistance and high strength is provided by this balanced dual-phase microstructure. These bars have yield strength above 550 MPa and tensile strength between 750 and 800 MPa. In environments with a lot of chloride, they are especially resistant to pitting, crevice corrosion, and stress corrosion cracking. The material retains good impact toughness, weldability, and fatigue resistance under demanding conditions, and the bright finish improves surface quality.
