Fatigue Properties of Case-Carburized SAE 4320
Previously, the strain-controlled fatigue properties of the high hardness case and the lower hardness core of carburized low alloy steels were compared. The properties of the case were developed through simulation by diffusing carbon completely through fatigue specimen blanks. The … 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
