WIPO Patent Application WO/2013/180027
Kind Code:
A1
Abstract:
[Problem] To provide a surface-treated steel sheet for a container, a method for manufacturing the same, an organic-resin-coated surface-treated steel sheet, and a metal can, the surface-treated steel sheet having excellent processing adhesion to a coating organic resin, without the use of chromium. [Solution] The surface-treated steel sheet for a container according to the present invention is a surface-treated steel sheet in which one or both sides of the steel sheet surface is nickel plated, the nickel plating having a fine-granular morphology in which the particle density is 2-500 particles/µm2 and the average particle diameter is 0.05-0.7 µm. The present invention is characterized in that the deposited amount of the nickel plating of the surface-treated steel sheet for a container is 0.1-12 g/m2, the nickel plating film contains metallic tin, and the amount of the metallic tin is 0.05-0.1 g/m2. The present invention is also characterized in that the organic-resin-coated surface-treated steel sheet is obtained by coating one or both sides of the surface-treated steel sheet for a container with an organic resin layer, and the metal can is obtained by processing the organic-resin-coated surface-treated steel sheet.
