by roll-forming (3 inch balls) or by forging (5 inch balls). In both cases, the balls are then quenched in water at an initial temperature of 50º C and then equalised, (i.e. natural cooled in open air), to a uniform temperature. For the 3 inch diameter balls, the time for each of these treatments is 80s and 40s, respectively.
