In this paper,3Cr2W8V die steel for casting of automotive parts was modified by Ti-Sr composite addition,and the results of high temperature wear test and thermal fatigue test were analyzed.The results show that the addition of Ti and Sr has an important effect on the wear resistance and thermal fatigue properties of 3Cr2W8V die steel.Compared with the 3Cr2W8V die steel without Ti and Sr,the wear volume,the average width and depth of the main crack for the steel with 0.3% Ti and 0.3% Sr respectively decrease by 35.7%,44.8% and 57.1%.The wear resistance and thermal fatigue properties of the die steel with 0.3% Ti and 0.3% Sr are improved.
