Tanvir Nickel Alloys, located in Cairo, Egypt, stands out as a top manufacturer and supplier of premium Super Duplex Steel Tubing. Known for its dedication to precision and durability, the company focuses on providing tubing that adheres to strict international standards. With state-of-the-art production facilities and rigorous quality control measures, Tanvir Nickel Alloys guarantees consistent performance across all its offerings. Catering to industries that require exceptional corrosion resistance and mechanical strength, the company has built a reputation as a reliable partner in supplying Super Duplex Steel Tubing for critical applications in challenging environments, ensuring longevity and safety in every project.
Super Duplex Steel Tubing boasts a well-balanced microstructure, featuring about 50% austenite and 50% ferrite, which delivers remarkable strength and resistance to corrosion. Typically, it contains 22–25% chromium, 4–5% nickel, 3–5% molybdenum, and trace amounts of nitrogen, all of which enhance its resistance to pitting and crevice corrosion. The mechanical properties are impressive, with a high tensile strength ranging from 770–850 MPa, yield strength between 550–620 MPa, and an elongation of 25–30%. This unique blend of alloying elements and microstructure ensures exceptional durability, making it perfect for high-pressure and chemically aggressive environments.
