Chrome steel balls are widely used in precision ball bearings, as well as, in a number of other industrial applications. Chrome steel balls have excellent surface quality, high hardness and high load bearing capacity, as a result of through hardening.

Only the finest quality chrome steel, produced in accordance with ASTM specification A-295, is used.  Small size balls are made from wire stock while larger size balls are hot forged from bar stock. Modern furnaces with precisely controlled atmospheres and temperatures are used for heat treating to assure uniform hardness and proper microstructure for each chrome steel ball. Throughout the manufacturing process, statistical process control assures tolerance accuracy, fine surface finish and consistent high quality.

Material Analysis:
Chrome balls are made from the following special chemical analysis.
All sizes and grades are manufactured from AISI Type 52100 steel.
