Abstract
A nickel coating and an aluminum layer are formed in this order on an inexpensive thin steel sheet made of a low-carbon steel, a low-chromium steel or a low-nickel steel. Then the nickel- and aluminum-plated thin steel sheet is subjected to a diffusion penetration treatment to form a mutually diffused layer over the entire surface of the thin steel sheet, thus providing a thin steel band which is excellent in heat-resistance, corrosion-proofness at high temperature and rigidity.
