What is Cold Drawn Steel Bar?
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 Process Of Cold Drawing Steel Bars
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. All Eaton Steel cold drawn bars are also produced with our in line proprietary surface inspection equipment. Eddy current, roto-bar testing or mag testing are also available in our off-line testing center and employed per your specifications. Machinability and improved chip formation are enhanced by the elevated physical properties.
