Induction Heating and Heat Treatment
Induction Case Hardening of Axle Shafts
This article describes the common types of automotive and truck axle shafts. It provides information on steels used for induction-hardened shafts, and on the manufacturing and induction hardening methods of axle shafts. The article discusses the effects of case depth, shaft length, and carbon content on torsional properties of axle shafts, and the effect of changes in shaft diameter and those of splines on torsional shaft performance. It also provides useful information on straightening and tempering of induction-hardened axle shafts, and describes an effective technique to ensure quality of induction-hardened axle shafts.
