Fatigue Performance and Cleanliness of Carburizing Steels for Gears

17FTM15

The cleanliness of steels used for gears is of great importance when looking to improve life of gears or increase loads. In this paper, carburizing steels with the same basic chemical composition, but with a varying cleanliness level, are compared. The investigation showed a good qualitative correlation between the fatigue performance and the inclusion assessment made by ultrasonic evaluation and SEM. The results also show that traditional micro-inclusion rating methods are not sensitive enough to give a good indication of material performance.
