Chrome alloy steel balls comprise about 90% of all balls manufactured. This material is a high carbon (1.00%), chrome (1.36%) alloy steel that will harden into the 60 - 65 HRC range when oil quenched from a soaking temperature of 1475 F. The hardness usually ends up at 62 HRC. The stress relieving or drawing temperature is 325 F.
