Heat Treatment

We provide a full range of general heat treating available; annealing, stress relieving, normalising, homogenisation, tempering, precipitation, etc.

Vacuum Furnace

Heat treating under a vacuum maintains the surface finish of components during treatment.
Vacuum heat treating is used for bright hardening and tempering, bright annealing, solution annealing of stainless steel, and vacuum brazing.

Induction hardening

Induction hardening is a process where the component is heated by electromagnetic induction. A high frequency current is passed through a coil that is in close proximity to the area to be heated. The heated area is then quickly quenched using water spray. The heating and quenching is very rapid and localised.

Carburising

A surface hardening treatment in which carbon is diffused into the surface of a low carbon/low alloy steel at high temperature (approx. (900C). After quenching the result is a component with high hardness on the surface, but with a softer, tough core.

Nitriding

Nitriding is a surface hardening treatment that introduces nitrogen into the surface of the steel at a relatively low temperature (approx. 520C). At this temperature the nitrogen reacts with alloying elements in the steel and forms a hard compound known as a ‘nitride’. Because of the low processing temperatures and the absence of quenching, nitriding is a very low distortion process in comparison to conventional heat treatment.

Carbonitriding

Similar to Carburising but as well as diffusing carbon into the steel and addition of nitrogen is made at the same time.
