Heat Treat a Part

In our over 50 years in heat treating we have continued to invest in technology, systems and our personnel to offer you the best solutions we can.  You can be confident your parts will be treated specifically to your needs.



Carburising and Carbonitriding

With carburising, carbon is diffused into the surface of low carbon/low alloy steel to achieve high hardness on the surface with a softer, tough core underneath.  Carbonitriding is very similar, but also has nitrogen diffused into the steel for steels with lower hardenability.  This is done using one of our four computer controlled sealed-quenched furnaces (integral quench), with tight control of carbon concentration, diffusion rates, temperatures, and quench variables, producing high quality carburising.

With this treatment you will get components with minimum distortion and optimum mechanical properties.  You will also find:

Induction Hardening

This is a rapid and localised process, minimising exposure of the surface to air which causes decarburisation.  Heat energy is induced into the part electromagnetically and then the heated area is quickly quenched using a water based spray quenchant.  You can induction harden the surface of many different products, including cylindrical components, pins, shafts, axles, sprockets, drive dogs, ratchet pawls, cam lobes, splines, and more.


We use one of our three Induction Hardeners, including a twin spindle CNC machine for higher volume processing.


This is a fast and effective process with quick turnaround.  You will get localised hardening to specific areas and less distortion than alternatives.  Heavy case depths are achievable and you will find this to be an economical option, especially with parts > 10kg.


Vacuum Processing

This is the ultimate method of surface protection, most commonly used for hardening high alloy steels.  With our computer-controlled vacuum furnaces you will have increased temperature uniformity and minimal distortion levels. 


You will also get clean, scale and discolouration free processing and no damage to polished or highly finished surfaces.
