Abstract
Official abstract text for this publication.
The present invention provides a steel sheet for a container including a cold-rolled steel sheet and a composite film formed on the cold-rolled steel sheet through an electrolysis process in a solution containing: at least one metal ion of an Sn ion, an Fe ion, and an Ni ion; Zr ion; a nitric acid ion: and an ammonium ion, in which the composite film contains at least one element of: Zr of 0.1 to 100 mg/m 2 in equivalent units of metal Zr; Sn of 0.3 to 20 g/m 2 in equivalent units of metal Sn; Fe of 5 to 2000 mg/m 2 in equivalent units of metal Fe; and Ni of 5 to 2000 mg/m 2 in equivalent units of metal Ni.
