Abstract

1. Process for the partial heat treatment of components made from cast iron materials with spheroidal graphite and a pearlitic basic structure, in which the parts to undergo heat treatment are austenitized by inductive heating in a temperature range 850 to 1000 degrees C and are subsequently left in a quenching medium maintained in a temperature range 180 to 450 degrees C until converted into a bainitic structure.
