Induction hardening steel to austenitic temperatures can result in temper back, or annealing of adjacent areas of the material that have been hardened previously. This is particularly important in the induction hardening of crankshafts, camshafts, gears and critical components. This publication discusses above mentioned effect along with some other important features of induction hardening and tempering, including overview of different magnetic flux concentrator materials and major concern when using flux concentrators in induction heat treating.

Magnetic flux concentrators (flux intensifiers) are widely used in metal heat treating. Presented here are some of the major factors that must be considered to properly apply different kinds of magnetic flux concentrators for induction heat treating, including surface and through hardening, annealing and tempering. Important considerations and common misconceptions are discussed in this article also.
