CAST BALL
Cast ball is a type of grinding ball made by combination of various chemical compositions which are treated with
metallic molding, heat process and selection.
Features of cast ball

Cast ball is divided into grades according to Cr(Chrome) content and the grades affect costs considerably.
Cr(Chrome) hardens up to the inner core, improves wear and corrosion resistance.

Carbon(C) content is approx. 1.8~3.5% and carbon increases product hardness to improve mechanical properties.
