Jiangyin Dongbang Steel ball Machinery Co., Ltd is a manufacturer of hot-rolled steel ball by national standards. The annual output of grinding balls is 60000 Tons. Our company choose the high quality special steel as a raw material, it fundamentally improves the quality of steel balls. 

Ball hot rolling process is a new technology it is the technical breakthrough of steel ball manufacturing process. And it is replacing casting steel ball and forging steel ball gradually. Parameters of hot rolled steel ball: 

1. The overall high hardness: Surface hardness of 57-68 HRC, volume hardness of 56-65 HRC, and the hardness gradient distribute evenly. 

2. High impact toughness: More than 12 J/CM2 

3. Low broken rate: Anti-broken and anti-broken off performance is 10 times of general casting steel ball, balls impact times over 20, 000 times, the actual broken rate is less then 1%, close to no broken.
