摘　　要：研究了新型热作模具钢的热处理工艺、组织与性能的关系，并与常用的热作模具钢进行比较。结果表明；ＣＨ７５钢具有较３Ｃｒ２Ｗ８Ｖ和Ｈ１３钢优异的回火稳定性和高温性能，适宜做工作温度为７００℃左右的热作模具。The relationship between the heat -treatment and the structure and properties of a new-type heatworking die steel CH75 was studied,and also makes comparison with commonly-used heat-working die steels. The result shown that this new-type steel CH75 is suited for making heat-working die with its working temperature at about 700℃,as it has better tempering stability and high-temperature properties.
