advantages of buying CR over HR for machining

Aug 24, 2015 · The cold rolling process sizes the steel to final dimension and provides a smooth, scale-free surface. Dimensionally, it will be within a few thousandths and will be relativeyl straight over a length. This makes CRS a good choice for simple parts with fairly loose tolerances as it can eliminate a lot of machining.Whats the Difference Between Hot and Cold Rolled Steel machining cold rolled steelCold rolled steel is essentially hot rolled steel that has gone through more processing.
