Abstract

PURPOSE: To provide excellent paint adherence, workability and corrosion-resistance, by performing tin plating, then forming the Fe-Sn alloy layer having specific range of Fe atom ratio by heating it, correcting the shape of the strip by rolling under light pressure and forming a chemically treated film on its surface.
CONSTITUTION: After the tin plating layer of a specific amount is formed on a cold rolled steel strip, the steel strip is heated at the predetermined temperature and the entire tin plating layer is made the Fe-Sn alloy layer of Fe atom ratio 40W80%. After the steel strip is rolled under light pressure and its shape is corrected, the chemical treatment of immersion in sodium bichromate solution or by electrolytic treatment, electrolytic treatment in phosphoric acid solution etc. is performed and the chemically treated film is formed on the surface of the Fe- Sn alloy layer.
