ABSTRACT:
A chromate surface treated steel sheet having very excellent paintability, corrosion resistance, and workability, more specifically surface treated steel sheets for paint coating, having very excellent properties, specifically with respect to corrosion resistance after paint coating, paint adhesion in services long after the paint coating (so-called secondary paint adhesion), corrosion resistance of paint coating defect portions, and resistance to secondary work cracking. The steel sheet contains not more than 0.15% carbon, 0.005 to 0.10% acid soluble aluminium, 0.5 to 20% chromium with the balance being iron and unavoidable impurities, and the chromate coating applied on the steel substrate comprises a metallic chromium layer in an amount ranging from 1 to 300 mg/m.sup.2, and a hydrated chromium oxide layer in an amount ranging from 5 to 50 mg/m.sup.2 in term of the metallic chromium contained therein.
