Manufacturing method for steel sheets for containers

A method of manufacturing a steel sheet for containers which has a chemical conversion coating formed on the steel sheet and containing 1 to 100 mg/m2 of zirconium metal and up to 0.1 mg/m2 of fluorine, the method comprising:

• forming the chemical conversion coating on the steel sheet by subjecting the steel sheet to immersion in a treatment solution containing zirconium ions, phosphate ions, phenolic resin and fluorine ions or to electrolytic treatment using the treatment solution;
• washing the steel sheet having the chemical conversion coating formed thereon with water at a temperature of 80° C. or more but not more than 95° C.;
• and
• drying the steel sheet,
• wherein the chemical conversion coating contains 0.1 to 50 mg/m2 of phosphorus and 0.1 to 50 mg/m2 of carbon.
