HUAFU forged steel balls are described for ball mills in mining, cement plants, steel mills and chemical industries. The stated hardness is 58HRC.
Match the ball diameter to the mill
The model description gives 20-160mm, while the title references 1-6 inches. Specify the exact delivered diameter and tolerance rather than assuming the two ranges establish identical size coverage.
- Forged steel ball is the product identity.
- Steel is the stated material.
- Ball-mill use is explicitly identified.
Review the metallurgical requirement
The microstructure is described as M+C. If that structure or the 58HRC hardness is an acceptance requirement, request the applicable batch report and test method for the chosen diameter.
Separate test claims from guaranteed life
Impact value, drop count and breakage figures need their test conditions and supply scope confirmed. Obtain current ISO documentation when required; a certificate label alone does not establish product certification or guarantee grinding-media life in your mill.
