To accurately express metal hardness, engineers use a standard process called rockwell testing. in the knife blade manufacturing business, hardness ratings follow a predetermined chart which is commonly called the rockwell c scale. the higher the number on the rc scale, the harder the steel.
Dec 09, 2009 this happens because of the difference in hardness between the balls and the shaft with the compression of the balls in the ball groove producing microscopic indentations. typically, the balls are going to be between 62 and 64hrc on the rockwell hardness scale. ... good control of the grinding process should allow for a small range of ball.
