Abstract
Disclosed is a thickness-reduced deep-draw-formed can, which is prepared by subjecting a resin-coated structure of a surface-treated steel plate comprising, as the substrate, a cold-rolled steel plate having a carbon content in the steel of 0.04 to 0.15% by weight and a manganese content in the steel of 0.3 to 1.0% by weight, an average crystal grain size not larger than 6.0 .mu.m and a tensile strength of at least 65 kg/mm.sup.2, to reduction of the thickness and deep-draw-forming. This can has a high pressure-resistant vessel strength, a high uniformity of the can plate thickness, a high adhesion of the coating and a high corrosion resistance in combination.
