N:i.-plated steel sheet and method of manufacturing battery can using the Ni-plated steel sheetA Ni-plated steel sheet provided in which thee occurrence of scratches at the time of forming a battery can is suppressed. Also provided is a method which includes a step where a surface of a. steel sheet is plated with Ni in a Ni adhesion amount of 0.3-2 µm, a step where the Ni-plated steel sheet is heated to 600-800'C to form an Fe-Ni diffusion layer as an outermost surface layer, and a step where the steel sheetrolled by temper roiling so as to adjust the Fe-Ni diffusion layer so that the steel sheet has the surface roughness Ra of 0.9-2.0 pm and the surface roughness Ry of 4,0-15 pm. A Ni-platedsteel sheet which includes an Fe-Ni diffusion laver as an outermost surface layer and in which the diffusion layer has the surface roughness Ra of 0.9-2,0 pm and The surface e oughness Ry of 4.0-lb pm and the diffusion layer has such an Fe/Ni ratiothat the Fe accounts for 20-50% in Auger analysis is subjected to drawing using a water•soluble liquid which contains water-soluble emersion as a press lubricant. |
