【Abstract】 The critical points of ZG35CrMnSi steel is determined by means of Formaster Digital. The heat treatment and distribution of quenched layer of the steel has been studied. Result shows that the quenched layer exceeds 24 mm under the optimized heat treatment process, that meets the needs of mechanical properties in use.更多还原
