摘　　要：通过进行SKD11钢和20CrMo钢高温性能试验,把试样按照压铸模的工作温度区间(20℃～700℃)进行加热——冷却循环。SKD11钢中由于ωCr=11.5%～13.0%,会提高材料抗高温氧化能力和抗热疲劳性能,使其抗高温氧化能力远好于20CrMo。而且未在SKD11试样表面发现热疲劳裂纹。SKD11试样的基体组织也没有明显变化。Through carry on SKD11 steel and 20CrMo steel high temperature performance test, by heating and cooling the samples between 20℃-700℃,because of ωCr=11.5%-13.0%, it can improve resistance of high temperature oxidation performance and hot figure performance of SKD11 steel, it does not find hot figure crack on the sample surface and the base structures still remain the original shape.
