With the development of wet ball mills, the advantage of forged grinding steel balls (made by skew rolling mills) is more and more obvious.

The carbon content between 0.6% and 1.1% and, due to the presence of other additional elements, after their standard heat treatment, all the ball zones –external and central –reach high hardness values over 60 HRC in the case of the 3-inch diameter balls.

Steel ball factors, which affect the bearing performance
