Additional Data on the Effect of Cooling Rate on the Fatigue Properties of Carburized Steels

In the previous post, the effects of a cooling rate change after carburizing, due to a change in steel bar diameter, on core fatigue properties was examined.  The data was developed for a Ni-Cr-Mo low alloy steel (SAE 4320), and … Continue reading

Comparison of Case Hardening by Carburizing Versus Surface Induction Hardening

In past postings, the case and core properties of case hardened steels have been discussed.  These discussions have included the fatigue properties of both carburized and surface induction hardened steels. Carburizing is usually employed on carbon or low alloy steels … 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

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
