Abstract
PURPOSE:To improve the product strength by making the number of drawn passes plural to reduce a reduction of area and performing cold drawing with an inlet side drawing temp. in respective passes kept lower than a specific temp. CONSTITUTION:Drawing is performed in a state where the number of drawing dies 2 on a drawing line of a steel stock 1 are increased and plural dies 2 are arranged in a straight line. In that time, an inlet side drawing temp. in respective passes is kept to be <=140 deg.C by setting a reduction of area per pass to a small value. Thus, the strength is stably obtained.
