Chrome Steel Grinding Media Balls Description

AISI Type 52100 Chrome Steel Grinding Media Balls are used in the dry grinding and milling applications where corrosion resistance is not required. When corrosion resistance is required, 304 or 316 stainless steel grinding media balls should be used. Compared to stainless steel balls, the Chrome Steel Balls offer superior wear resistance, high hardness and high load bearing capacity as a result of through-hardening. Standard balls meet bearing ball grade 1000. Other grades are available upon request.
