What is mean by super duplex steel?

Super duplex steel is a high-performance alloy that combines the properties of both austenitic and ferritic stainless steels, offering Excellent resistance to corrosion and high strength. Typically containing around 25% chromium and 7% nickel, it is designed for use in harsh environments, such as chemical processing and marine applications. Its unique microstructure provides enhanced durability and resistance to stress corrosion cracking, making it ideal for demanding applications. Super duplex steel is often used in piping systems, valves, and other equipment that require superior mechanical properties and corrosion resistance.
