Confirm the requested cast ball diameter and hardness before approving a high-hardness grinding media order.
Diameter limits
The title gives 20–150 mm while the detail states 20–120 mm and actual cast entries have specific sizes. Verify title-only diameters separately rather than presenting the full requested span as available cast configurations.
Hardness evidence
HRC60–65 appears in the title without a supplied test result. Agree actual alloy, hardness method and acceptance for the selected lot; a chromium-labelled menu entry alone does not prove a particular tested hardness.

- Mill wear evaluation
Performance boundary
Define the operating trial before approval. High-hardness and wear-resistant labels establish no breakage limit, media consumption or guaranteed service life.
