Bluewater’s Carbonitriding is a surface hardening process that provides a thin, high hardness case on lower hardenability steels. This thermochemical treatment diffuses both carbon and nitrogen into the surface of the component simultaneously.  The use of nitrogen to increase the hardenability of the carburized case allows plain carbon or lower alloy steels to be case hardened successfully with full transformation to martensite in order to maximize the case hardness and obtain the best possible mechanical properties.  The process adds wear resistance and improvements in strength to the case.
