Forged grinding ball is resistant to abrasion, and won't deform and crack. That can be fully shown from the aspects of high overall hardness, high surface hardness of up to 57HRC to 67HRC, high volume hardness as large as 56HRC to 64HRC, uniform hardness distribution, high impact toughness of greater than 12J/cm², low breakage rate, peel fragmentation resistance property of over 20000 times, and the actual breakage rate not greater than 1% and close to 0.
1) High Hardness: surface hardness of forged and rolling ball is to 58-68 HRC and volume hardness is to 57-63 HRC
2) High Impact Toughness: impact toughness is more than 12 J/cm2
3) Low Broken Rate: the actual broken rate is not higher than 1%
4) Wear-resistant: loss of grinding media is less than 80g/ton
