| Low Chrome Cylpebs | 65-95g Cylpebs/Ton Cement | <1% | 12×18-35×40 |
| Micro Cylpebs | 6×6 8×8 10×10 12×12 15×15 | ||
4. The difference of the forged ball and cast ball
① Different production line
② Different raw material
③ Different chemical element
④ Different core hardness and core hardness
5. Packing
