CHROME STEEL BALLS AISI 52100 UNI 100C6
These balls are normally used in precision ball bearings and many industrial applications.
The balls made of this kind of 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.
