B2 B3 Forged Steel Grinding Ball | Mining Ball Mill Hardness and Material Selection
Grinding balls are described as solid round steel with a highly polished surface. The actual selection is Other grit with Steel material, while the body model lists B2, B3, B4, 45#, 71Mn and high-chromium alternatives.
Select the required B2 or B3 composition and ball diameter before applying catalogue properties. Hardness entries of 60–66HRC, 55–60HRC and 58–62HRC are not mapped to an individual material or size.
For a mining ball mill, define the operating duty and inspection requirements. No wear-rate or impact test demonstrates title resistance claims. Request chemistry, hardness profile and dimensional records; the ISO3290:2001 and G3–G1000 labels need a selected tolerance specification rather than assumed compliance.
