In the event that in a heat-treating operation the components suffered from decarburization (loss of carbon content) of the surfac

It is a thermal process of simultaneously diffusing both carbon and nitrogen into ferrous alloys under partial pressure.

Hardening is one of the oldest metallurgical processes known to man, originally in the form of heating a sword in the fire and then throwing it into the lake to make it harder.

Tempering is almost always required after hardening (both in an atmosphere furnace as well as in vacuum, as described further)

Nitrex will use this technique occasionally when sand blasting would be considered too rough.
