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

Effect of Cooling Rate after Carburizing on the Fatigue Properties of Carburized Steels

In earlier posts, the fatigue properties of various carburized low alloy steels were examined.  Both case and core properties were evaluated.  Since carburized components are manufactured in various section sizes, it can be expected that cooling rates in the cores … Continue reading

If Fatigue Data is Not Available, Is There a Means of Estimating Fatigue Performance?

Detailed fatigue data for a given combination of steel grade and processing offers the best means of determining fatigue performance when designing an automotive component.  However, in some instances, where only mechanical properties and hardness are available, methods have been … Continue reading
