We specialize in delivering precision-engineered solutions tailored for critical industrial applications. Our Duplex Steel Foil is crafted using cutting-edge technology and rigorous quality controls, ensuring it boasts superior corrosion resistance, impressive strength, and outstanding durability. With its unique dual-phase microstructure—featuring both austenitic and ferritic phases—Duplex Steel truly offers the best of both worlds. At Nial, we provide foil in a variety of thicknesses and specifications, catering to industries like chemical processing, marine, oil & gas, and paper manufacturing, all while ensuring top-notch performance in even the toughest environments.
Typically, Duplex Steel Foil contains around 22–25% chromium, 4–7% nickel, 3% molybdenum, and a balanced amount of iron, along with nitrogen to boost its mechanical properties. This blend gives it remarkable strength—about twice that of standard austenitic stainless steels—and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Its mechanical properties include a tensile strength of up to 800 MPa and a yield strength of around 550 MPa, along with good elongation and weldability. Plus, the foil form is lightweight and flexible, making it perfect for precision components without sacrificing mechanical integrity.
