These balls are normally used in precion ball bearings and many industrial applications.

The balls made of this kind material feature excellent surface finish, considerable hardness and a high load carrying capacity, as well as excellent wear and deformation resistance.

Chrome steel balls are through hardened in order to achieve the maximum mechanical strenght.
