The turned and polished round bars have similar mechanical properties to the same hot rolled bars, but show smooth, bright surface finish and higher dimensional accuracy. They are widely used for surfaces requiring no decarburization, such as in induction hardening, and when the surface must be free of surface defects, such as cold drawing.
