Product Description

Forged Steel Ball Features and Advantages:
Concentrating on wear-resistant grinding material for 28 years, Huamin Brand steel grinding ball is excellent in surface quality, hardness, and resistant to impact and abrasion. It won't crack and lose circularity easily.
1) High Hardness: Huamin forged grinding steel ball has high hardness: Surface hardness can reach to 55-67 HRC, volume hardness 56-64 HRC
2) High Impact Toughness: Impact toughness is more than 12 J / cm2.
3) Low Broken Rate: Peel fragmentation resistance property of over 20000 times. The actual breakage rate is less than 1% and close to 0.
