Based in Kolkata, India, Neil Metals is a well-known producer and supplier of Super Duplex Steel Bars and Rods, with a reputation for providing high-end goods to a range of industries. Super Duplex Steel Bars and Rods from Neil Metals, which specialises in high-performance alloys, offer exceptional strength, corrosion resistance, and durability in demanding conditions. Because their products are made in accordance with international standards, they can be used in chemical, marine, and offshore applications. With a dedication to client satisfaction, Neil Metals provides accurate engineering, prompt delivery, and constant quality, effectively and dependably serving both domestic and international markets.
Super Duplex Steel Bars and Rods have exceptional resistance to pitting, crevice, and stress corrosion cracking because they normally contain 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and additional nitrogen and manganese. They have an elongation of 25%, a yield strength of ≥550 MPa, and a tensile strength of about 800 MPa. The alloy is ideal for harsh environments because of its dual-phase (austenitic-ferritic) microstructure, which improves mechanical properties. These bars provide outstanding fatigue strength and weldability while remaining stable at high temperatures and pressures.

Super Duplex Steel Bars and Rods are extensively utilised in heat exchangers, desalination plants, chemical process equipment and offshore oil and gas platforms because of their exceptional resistance to stress cracking and corrosion caused by chloride. They are perfect for pulp and paper, power generation, and marine environments where corrosion resistance and mechanical strength are essential. Shafts, valves, pressure vessels, and subsea equipment are some more uses. Super Duplex Steel’s durability makes it appropriate for high-load structures in corrosive environments, guaranteeing performance, longevity, and safety in demanding industrial operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
