What it Carbonitriding?

Carbonitriding is a similar process to carburizing, chemically changing the composition of the surface. Carbon and nitrogen are diffused; generally producing a much shallower case depth upon hardening than a carburized component, although the hard surface is supported by the ductile "core" material.

Components up to 0.6M in diameter and up to 1.2M long can be treated vertically using special jigging to minimise distortion.
