ABSTRACT:
A method for producing a thin tin and nickel plated steel sheet having a surface structure in which the distribution of numerous nodules of metallic tin are observed by using an electron microscope on an iron-tin-nickel alloy layer formed on a steel sheet which comprises electroplating nickel on the steel sheet which is anodically treated in an alkaline electrolyte with a pH of above 10 followed by electrotinplating the nickel plated steel sheet, reflowing, quenching, and then chromate treating the tin and nickel plated steel sheet.
This tin and nickel plated steel sheet is suitable for welded can materials since it is excellent in corrosion resistance after lacquering and weldability.
