52100 hardened chromium steel balls, they show excellent hardness, wear resistance, very good surface finishing and dimensional stability.
AISI 52100
Chrome steel balls are through hardned in order to achieve the maximum mechanical strength. Balls made of this kind of material feature excellent surface surface finish, considerable hardness and high load carrying capacity, as well as excellent wear and deformation resistance. These balls are normally used in precision ball bearings, valves and many other industrial applications.
