A.Diameter: 20~130mm
B.Parameters of hot rolled steel ball:
1. The overall high hardness: surface hardness of 57-67 HRC, volume hardness of 56-64 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.
