Properties & Typical Applications

Type 2207 combines many of the most beneficial properties of ferritic and austenitic steels and offers excellent resistance to spot, gap and uniform corrosion due to its high chromium and molybdenum content. The biphase microstructure ensures that the steel has high stress corrosion cracking resistance and high mechanical strength. Applications in the oil and gas industry; Heat exchanger pipes, water treatment and water supply systems, desalination (desalination) equipment; Mechanical and structural components with high strength and high corrosion resistance are required; Burning (waste) gas purification equipment.
