The steels for cold deformation possess a chemical composition with low carbon and an analytical balance that improves the possibility of obtaining cold forged pieces even with large deformations. The steel for bearings most commonly used for the production of ball bearings, rollers, rings, and pieces for bearings, both by chip removal and cold deformation.
