Abstract
In the method according to the invention, a wire () provided with teeth () passes sequentially through a first inductor () and a second inductor (). The inductors () function at different frequencies and generate different temperatures. The first inductor () heats in particular the base section (), which is not to be hardened, to a high temperature below the austenitizing temperature range. The second inductor () heats the teeth () to a still higher second temperature within the austenitizing temperature range. Defined, hardened teeth of consistently high quality result at quenching.
