Heat treating ovens may perform a number of heat processes, including quenching, case hardening, precipitation hardening, tempering and annealing. Quenching is the process of cooling a metal at a rapid rate. In ferrous alloys, this process will produce a harder metal, while in non-ferrous alloys, like copper, aluminum or nickel, it will produce softer metal.

Case hardening is a thermochemical diffusion process in which an alloying element, like nitrogen or carbon, diffuses into the surface of a monolithic metal. The result is a solid solution that is harder than the original material, which improves its wear resistance without compromising its toughness.

Precipitation hardening, also known as age hardening, is a heat treating process that increases the yield strength of most malleable materials. These materials include most structural alloys of aluminum, nickel, titanium, magnesium and some steels and stainless steels.

In superalloys, precipitation hardening is known to produce yield strength anomaly, which provides excellent high temperature strength. Tempering increases the toughness of iron-based alloys. Usually performed after hardening to reduce some of the excess hardness, tempering is completed by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air.

Finally, annealing is a rather general term that refers to the heating of a metal to a specific temperature and then letting it cool very slowly, at a rate that will produce a fine microstructure. The microstructure will be either partially or fully separated from the constituents.

Heat treating ovens are employed with this technique most often to soften a metal for cold working, to improve machinability or to enhance properties like electrical conductivity.

Heat treating ovens can generally be split into two groups: batch ovens and continuous ovens. Batch ovens are usually loaded and unloaded manually. Continuous ovens, on the other hand, have an automatic conveying system that provides a constant load into the oven chamber.

Industries in which heat treating ovens are employed include: aerospace, automotive, composite and specialty materials, medical, dental and military and defense. Heat treating serves these industries well by providing them with glass and metal that has improved strength, hardness and toughness.
