Super Duplex Steel is a high-performance stainless steel characterized by its unique microstructure, which is a nearly equal mixture of austenite and ferrite phases. This dual-phase structure gives it superior mechanical properties, including high strength, toughness, and excellent resistance to both corrosion and stress corrosion cracking. Composed of elements such as iron, chromium, nickel, molybdenum, and nitrogen, the addition of nitrogen enhances its strength and pitting resistance. Super duplex steel is widely used in the offshore oil and gas industry for subsea pipelines, risers, and platform structures, withstanding the high pressures, low temperatures, and corrosive seawater of the deep sea. In the chemical industry, it is used for reactors, heat exchangers, and pumps handling aggressive chemicals. In the desalination industry, super duplex steel components are crucial for the long - term operation of seawater desalination plants, enduring the harsh conditions of saltwater treatment. XINTONGDA's super duplex steel products undergo strict quality testing and advanced manufacturing processes, ensuring they meet the highest international standards for strength, durability, and corrosion resistance, and are available in various forms, including plates, bars, and pipes, to serve different industrial needs.
