ABSTRACT:
Method of straightening a metal bar in which the metal bar is straightened by transporting the metal bar between a pair of rollers at a first straightening pressure. An outer layer portion of the metal bar is then removed in order to provide the metal bar with a reduced diameter and a substantially round cross-section. The metal bar is then again straightened by transporting the metal bar between a pair of rollers at a second straightening pressure. Subsequent to such straightening step, the metal bar desirably is heat treated under stress relieving conditions.
