Heat treating is a process used to alter the physical, and sometimes chemical properties of a material, where the most common application is metallurgical.

Heat treatment involves the use of heating, to extreme temperatures, to achieve a desired result such as hardening of a material. Q2 Artificial Lift Services' Heat treating technique utilizes case hardening, precipitation strengthening, tempering, normalizing and quenching.

It is noteworthy the term heat treatment applies only to processes where the heating is done for the specific purpose of altering properties intentionally.
