Strength and Fatigue Life versus Carbon Content at High Hardness (60 HRC)
The strength, fatigue and hardness data for several iterations with a high hardness level, around 60 HRC are shown in Table 1. The steels in these iterations are both plain carbon and low alloy grades with carbon contents ranging from … Continue reading
Comparison of the Case and Core Properties of Carburized Steels
In recent postings, the strain-controlled fatigue properties of the high-hardness case and low-hardness core of induction hardened steels were compared. It was shown that at short lives, the softer core outperformed the high-hardness case. At long life, the fatigue properties … Continue reading

Further Comparisons of the Case and Core Properties of Induction Hardened Steels
In the last posting, the fatigue properties of surface induction hardened 1050 axle shafts were presented. Strain life data showed that in the short life regime, the fatigue properties of the low hardness core were better than those of the … Continue reading
