DIN 41Cr4和DIN 42CrMo4材料已广泛应用于汽车驱动元件。虽然42CrMo4比41Cr4昂贵，但从材料性能方面来说，它更好。在这项研究中，这两种材料通过在850摄氏度的连续炉中进行热处理，并在90摄氏度的油中淬火。在不同温度下回火后，测定每个回火温度下的机械性能。两种材料的材料性能进行了比较。结果表明，41Cr4和42CrMo4的相同的机械性能可以通过将41Cr4的回火温度比42CrMo4低约50 ℃来实现。除了机械试验外，还对两种材料进行了疲劳试验。绘制Weibull分布图。结果表明，42CrMo4材料的使用寿命比41Cr4材料高。
DIN 41Cr4 and DIN 42CrMo4 materials have been widely used in automotive driving elements. Although 42CrMo4 is more expensive than 41Cr4, it is more preferable in terms of material properties. In this study, these two materials were heat treated by austenitizing in a continuous furnace at 850 degrees C and quenched in oil at 90 degrees C. After they were tempered at various temperatures, mechanical properties were determined for each tempering temperature. The material properties for both materials were compared with each other. Results indicated that same mechanical properties for 41Cr4 and 42CrMo4 can be achieved by tempering 41Cr4 about 50 degrees C lower temperature than for 42CrMo4. In addition to the mechanical tests, fatigue tests were performed for both materials. Weibull distributions were plotted. Results indicated that 42CrMo4 had a longer life than 41Cr4 material.
