摘要
Coated steel sheet of high corrosion resistance comprises a sheet of steel containing not more than 0.1% by weight of carbon, 0.005 to 0.08% by weight of soluble aluminum and 0.2 to 20% by weight of chromium, the balance being iron and unavoidable impurities. The steel carries a nickel or nickel alloy layer formed on at least one surface thereof and having a thickness of 0.001 to 1.5 microns and a layer of tin formed on the nickel or nickel alloy layer and having a thickness of at least 0.05 micron. A method of producing it is also disclosed.
