Cold drawn steel bar is a kind of steel bar product processed by cold drawing process. In the cold drawing process, the low carbon steel bar is placed on the cold drawing machine, and through the way of strong drawing to make it through the mold hole smaller than the diameter of the original steel bar 0.5 to 1.0 mm, so that the steel bar is drawn into a smaller diameter steel wire.
In this process, the steel bar will produce transverse compression and longitudinal tensile, and its internal lattice will slip, so that the tensile strength is significantly increased, usually by 50% to 90%, but the plasticity will be reduced, and the hardness will be increased.
