Text Box: PROCESSES
Text Box: Carbonitriding is a modification of the carburizing process.  Nitrogen, formed by the dissociation of ammonia, is diffused into steel surfaces along with carbon.  This has the effect of increasing the hardenability of the case of low carbon, mild steels and free cutting steels.

Lower alloy case hardening steels such as 8620 or Hollow Bar may be carbonitrided.  However, higher alloyed case hardening steels are not suitable for carbonitriding as they are likely to form microstructures of lower hardness (retained austenite).

Case depths frequently undertaken:  0.15-1.0 mm.
