Abstract:
Disclosed is a steel sheet for containers that maintains excellent corrosion resistance even when a surface treatment that replaces a chromate treatment has been conducted, and that has excellent film adhesion qualities and appearance. This steel plate for containers has, on at least one surface thereof, a chemical conversion coating including at least two coatings selected from a zirconium coating that contains zirconium and has a metal zirconium content of 0.1-9 mg/m2, a phosphate coating that contains phosphoric acid and has a phosphorous content of 0.1-8 mg/m2, and a phenolic resin coating that contains phenolic resin in an amount of 0.5-8 mg/m2 in terms of carbon, the percentage of the area of the surface of the chemical conversion coating layer having particles Of a prescribed size being 0.1-50%.
