Cold-Drawn Steel Bar Description
Cold drawing hot rolled bars is accomplished by pulling (drawing) a bar through a die which is smaller than the incoming hot rolled size. The “cold working” process improves the dimensional tolerances of the bar, the straightness, and the surface appearance and enhances the physical properties of the steel.
