Super Duplex Steel is a high-performance stainless steel alloy known for its exceptional strength, corrosion resistance, and durability. It is a two-phase (austenitic-ferritic) microstructure alloy, meaning it contains an approximately equal balance of ferrite and austenite, which gives it superior mechanical and chemical properties compared to conventional stainless steels.
These steels are commonly used in industries such as oil and gas, chemical processing, desalination plants, and marine applications, where high strength, toughness, and resistance to corrosion are critical. Duplex and Super Duplex steels also offer excellent weldability and improved mechanical properties, making them ideal for demanding and high-stress applications.
