HRC55–65 Cast Carbon Steel Grinding Ball Requests | Black Media for Gold and Copper Ore Mills
Round black grinding media has actual cast Cr2–3% and Cr10% models, with forged C45, B2 and B3 choices in the same selector. The body size range reads 20–120mm and identifies casting for mining use.
Select a cast model and precise diameter, then agree hardness and chemistry acceptance. HRC55–65 occurs in the title without a body test value. It should not be assigned to all listed chromium or forged grades.
For gold or copper ore milling, provide the duty and inspection method. No validated wear, breakage or service interval is supplied. Request selected-batch analysis and hardness records rather than assuming title high-hardness wording or broad standard names establish a measured mechanical result or a universal grinding outcome.
