Title:
TIN-PLATED STEEL SHEET AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2010/005041
Kind Code:
A1
Abstract:
Provided is a tin-plated steel sheet having a plated layer containing Sn with a coated weight of Sn of 0.05 to 20 g/m2 per side on at least one side, a first chemical treatment film containing P and Sn with a coated weight of P of 0.3 to 10 mg/m2 per side on said Sn-containing plated layer, a second chemical treatment film containing P and Al with a coated weight of P of 1.2 to 10 mg/m2 per side and a coated weight of Al of 0.24 to 8.7 mg/m2 per side on said first chemical treatment film, and a silane coupling agent treatment layer with a coated weight of Si of 0.10 to 100 mg/m2 per side on said second chemical treatment film.  With said steel sheet, the deterioration in appearance and reduction in paint-adhesion properties due to oxidation of the tin-plated surface is suppressed without using Cr, and the chemical treatment can be carried out inexpensively.
