Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material.


Annealing is achieved with heat treatment processes that require a neutral (or inert) controlled atmosphere.

Brazing allow diverse configurations of parts, dissimilar metals and non-metals of non-uniform thickness to be joined.

Carburizing & Carbonitriding
A carburizing atmosphere must be able to transfer carbon (also nitrogen in the case of carbontriding) to steel surface.

The use of nitrogen for gas wiping of galvanized strip and wire has been widely adopted to give a better surface finish.
Neutral hardening is a heat treatment procedure for steels with the aim to produce a martensitic microstructure.
 Nitriding & Nitrocarburizing
These processes involve the diffusion of nitrogen into the surface layers of a low carbon steel at elevated temperature.
 Quenching & Cooling
The use of gas quenching in a vacuum furnaces has advantages over both conventional processing and liquid quenching
Sintering produces parts that are harder (martenistic) and/or tougher (martenistic/bainitic) by controlled the cooling rate.
 Sub Zero Treatments
Use a moderately cold process for stabilization and austenite removal or deep cold to improve wear resistance.

Other Applications
These range from Autoclaving to Hot Isostatic Pressing (HIP)
