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.
