摘要
研究了４４ＣｒＭｎＭｏ钢在不同淬火温度下所显未的组织和性能，选择其最佳的淬火温度（９００℃），采用煤油＋空气直生式渗碳气氛进步渗碳、淬火低温回火，使４０ＣｒＭｎＭｏ用制颗粒模的质量达到国外同类产品的水平．
The differenf structures and properties of 40CrMnMo steel was studied under different quenching temperature. The best quenching temperature is 900℃ with kerosene directly generating carburizing atmosphere and optimum quenching temperatute, this prorluct can get best quitity.
