The diameter range is from 15mm to 155mm.
Our steel balls have following advantages:
accurate dimension,round geometry,high hardness and good mechanical properties,and wear resistant,
The characteristics are below:
1.Overall high hardness:the surface hardness can reach 55-65 HRC,volume hardness can reach 54-62 HRC,and the hardness gradient is uniform.
2.High impact toughness:it is more than 8J/cm2.
3.Low breakage rate:Performance of peel &breakageresistant is more than 10 times than that of traditional cast steel balls.There is almost no breakage when balls impact more than 5000 times.Actual breakage rate is less than 1%.
