Abstract
A highly corrosion resistant steel sheet for fuel tank comprising a lowermost layer of Zn or Zn-based plating layer deposited on each side of the steel sheet; a chemical conversion film deposited on each of the Zn or Zn-based plating layer; a metal powder-containing organic resin film deposited on one of the chemical conversion film, said metal powder-containing organic resin film containing Al and Ni metal powders and an amine modified epoxy resin; and a silica-containing organic resin film deposited on the other chemical conversion film, said silica-containing organic resin film containing at least one resin having at least one functional group selected from hydroxyl group, isocyanate group, carboxyl group, glycidyl group, and amino group; silica; and a lubricant. The steel sheet of the present invention has excellent corrosion resistance, press workability, resistance weldability and brazing ability, and therefore, the steel sheet of the present invention is particularly useful when it is used in contact with an alcohol or an alcohol-blended gasoline.
