This study elucidates the effect of wear resistance in Forging S45C. Three wear factor which are wear loss, coefficient of friction and friction force could conduct an experiment of wear-resistance test. First of all, wear test of ball-on-disk has been performed using steel balls to determine the variation of wear characteristics. Finally, the coefficient of wear was calculated by the Archard wear equation in hot forging S45C.
