Stress Relieving

As the name of the process clearly indicates, Stress Relieving is used to reduce the residual stresses in the microstructure

Age/Precipitation Hardening

Age or Precipitation Hardening (also Aging) is a change in material properties (generally hardening)

Austenitizing

Austenitizing is a process designed to induce the formation of austenite on the alloy.

Carbon Restoration

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

Vacuum Hardening

Vacuum Hardening is an improvement over Conventional Hardening in that the components’ surfaces are protected from possible negative effects of exposure

Vacuum Tempering

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

Vacuum Annealing

This premium quality Vacuum Annealing method protects the components’ surfaces from chemical reactions

Vacuum Carbonitriding

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

Vacuum Carburizing

Vacuum carburizing is a state-of-the-art thermal process where carburizing is effected under very low pressures.

Glass Beading

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

Shot Blasting or Peening

When tiny steel balls are used the process of blasting parts using this medium will be called shot blasting or peening.

Sand Blasting

Depending on the need, the technique is used either before heat treatment (preparation) or after (e.g., removal of oxidation).

Cryogenic Treatment/Freezing

After a successful quench and temper, it is frequently desirable to subject the work piece to a cryogenic treatment

Straightening

Certain types of components, particularly longer objects such as shafts, tend to distort in high temperature treatment.
