Document Type and Number:
WIPO Patent Application WO/2010/005042
Kind Code:
A1
Abstract:
Disclosed is a tin-plated steel plate characterized in that the tin-plated steel plate comprises a steel plate, an Sn-containing plating layer provided on at least one side of the steel plate at a coverage of 0.05 to 20 g/m2, in terms of Sn, per side of the steel plate, a first chemical converted film provided on the Sn-containing plating layer and containing P and Sn, the coverage of P being 0.3 to 10 mg/m2 per side, and a second chemically converted film provided on the first chemically converted film and containing P and Al, at a coverage of 1.2 to 10 mg/m2, per side, in terms of P and at coverage of 0.24 to 8.7 mg/m2, per side, in terms of Al.  The tin-plated steel plate can realize the suppression of a deterioration in appearance and a lowering in coating material adhesion caused by oxidation of the surface of tin plating without using Cr and, at the same time, can realize chemical conversion treatment at low cost.
