Metal Heat Treating Services

Metal heat treating processes alter the physical and, sometimes, chemical properties of metal materials to improve hardness, toughness, ductility, or other mechanical properties. Petersen Precision can provide the heat treating processes you need to enhance the physical characteristics of metal parts produced via our fine blankingCNC machining and CNC turning, and other fabrication processes,

At Petersen Precision, we work with trusted standard atmosphere and vacuum oven heat treaters in addition to NADCAP-certified third-party vendors—both local and national, as your project requires—to heat treat your parts to match your specifications.

Heat Treatment Process Options

Based on your metal heat treating service requirements, we will pair your project with the subcontractor best suited to the job. With our large network of proven vendors, you can trust that we're bringing the right people to the table so you get the high-quality heat-treated parts you need quickly and cost-effectively.

Most heat treatment processes utilize extreme heat and extreme cold to alter the crystalline microstructure of the work material to achieve the desired result. Standard metal heat treating processes include:


Annealing is a heat treatment process that alters a material's microstructure to change its mechanical or electrical properties. Typically, annealing is used in steels to reduce hardness, increase ductility, and help eliminate internal stresses. 


Normalization metal heat treating processes, the treated material obtains an increased fine-grained homogenous structure, providing predictable properties and machinability standards.


Once a part has reached its correct temperature, quenching cools the metal to room temperature, preparing it for future work. Quenched steel is typically harder and less ductile than it was prior to being heated, which is why quenching precedes other heat treating processes such as tempering, aging, annealing, or normalizing.


After a metal part is quenched, it requires tempering to increase its strength, which further hardens and increases the material's toughness. Tempering is best used on metal products such as fasteners and knives that encounter regular stress.


Precipitation metal heat treating processes age harden the material through elongated elevated heating temperatures, which allow the precipitation process to occur. Precipitation hardening is used to increase the overall strength of the metal.


Metal hardening heat treatment processes heat the metal to a point where solute-rich precipitates are dissolved. The subsequent cooling process provides increased strength, toughness, and durability.


When combined with cold work and grain size refinement, thermal strengthening can significantly improve parts and components' strength and ductility.
