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
Annealing is achieved with heat treatment processes that require a neutral (or inert) controlled atmosphere. |
| | Brazing
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. |
| | Galvanising
The use of nitrogen for gas wiping of galvanised strip and wire has been widely adopted to give a better surface finish. |
| | Hardening
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
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 stabilisation and austenite removal or deep cold to improve wear resistance. |
| | Other Applications
These range from Autoclaving to Hot Isostatic Pressing (HIP) |
