Effect of Steel Composition on the Case and Core Fatigue Properties of Low Alloy Carburized Steels
In earlier posts, limited data indicated that the fatigue properties of the cores of carburized components do not vary significantly with the composition of low alloy steels. There was evidence, however, that the fatigue properties of the cases of carburized … Continue reading

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
