Super Duplex Steel Foil is an advanced material composed primarily of chromium (22-25%), nickel (4.5-6.5%), molybdenum (3-5%), and nitrogen, with smaller amounts of manganese, silicon, and carbon. This unique composition ensures high corrosion resistance, particularly against pitting and stress corrosion cracking. It boasts impressive mechanical properties, including a high tensile strength of 620-800 MPa, a yield strength of at least 450 MPa, and excellent elongation (25-30%). The material’s dual-phase microstructure offers superior strength and durability, making it ideal for harsh environments like marine and chemical industries.
