Tech Talk: Nitriding for Crankshafts
Nitriding on alloy steels has many advantages. In order to best apply the many forms of nitriding; Ion Plasma, gas deep case…to name a few, it is important to understand the service requirements, coupled with the desired surface and core properties of the alloys.
For example, deep case nitriding is widely used to provide a deep, hard bed for roller bearing races. Gas deep case nitriding is required in order to survive the very high unit loading of the harder small diameter rollers. This application also needs the added compressive strength of deep case to this bed to minimize the Brinell effect.
