Steel H13 (AISI) is one of materials which is widely used in making hot -working die.
H13(美国钢号)是使用最广泛的热作模具钢之一。
The high temperature wear property of a new type precision cast hot-forging die steel was studied, and compared with that of H13 steel. The mechanism of the high temperature wear was discussed.
研究了新型精铸热锻模具钢的高温磨损性能，并与H13钢进行对比探讨高温磨损机理。
The results show that the H13 steel treated by new process has higher hardness and heat-fatigue property. The service life of hot-forge die is prolonged.
结果表明：h13热锻模具钢经此工艺处理后，具有较高的硬度和热疲劳性能，延长了模具的使用寿命。
