In the present work the thermal fatigue resistance of a typical hot work tool steel was studied. The material was subjected to salt quenching, by cooling the specimens in two different ways. The first cooling cycle produces a coarser microstructure than the second one, and induces the formation of upper bainite. While the thermal fatigue crack density is the same in the two materials, a clear difference in their propagation was found. The coarser microstructure and the presence of upper bainite tend to reduce the thermal fatigue resistance.
