Title:
STEEL SHEET FOR CONTAINER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2011/118588
Kind Code:
A1
Abstract:
Disclosed is a steel sheet for a container, which comprises, on at least one surface of the steel sheet, a plating layer that contains nickel in an amount of 300-1,000 mg/m2 in terms of Ni metal. The steel sheet for a container also comprises a chemical conversion coating film that is formed on the steel sheet by carrying out immersion or cathodic electrolysis in a solution that contains Zr ions, F ions and phosphate ions. The Zr metal amount in the chemical conversion coating film is 1.0-50 mg/m2, and the chemical conversion coating film contains phosphate compounds in an amount of 0.5-25 mg/m2 in terms of P. The atomic concentrations of F in a plane at a depth of 2 nm and in a plane at a depth of 4 nm as determined by XPS analysis are 2 at% or less, said planes being obtained by sputtering.
