The thermal fatigue (TF) performance of H13 hot work die steel is the main factor that affects the service life of the die. Brief detail of status and evaluation method of thermal fatigue performance of hot-work die steel are described. At the same time, the factors affecting TF performance and methods to improve TF performance are discussed. Experimentally analyzed the performance and the influence of microstructure evolution, crack initiation and propagation on TF. In addition, summarized the trend of TF research on hot work die steels is prospected.
