Abstract

A method is provided for making a steel sheet suitable as a can material. The method includes a step for hot rolling a steel slab to a strip having a thickness of less than about 1.2 mm, a step for coiling the strip into a coil at a temperature range between about 600.degree. and 750.degree. C., a step for pickling the coil with an acid, and a step for cold rolling the coil at a rolling reduction rate of about 50 to 90 percent, wherein the steel slab contains about 0.0020 weight percent or less of carbon, about 0.020 weight percent or less of silicon, about 0.50 weight percent or less of manganese, about 0.020 weight percent or less of phosphorus, about 0.010 weight percent or less of sulfur, about 0.150 weight percent or less of aluminum, about 0.0050 weight percent or less of nitrogen, and the balance iron and incidental impurities. A steel sheet suitable as a can material is also provided by this method.
