High-quality inspection service that you can depend on
Heat Treating is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. It is often associated with increasing the strength of the material, but it can also be used to alter certain manufacturability objectives such as improve machining, improve formability, or restore ductility after a cold working operation. It not only can help other manufacturing processes but can also improve product performance by increasing strength or other desirable characteristics. There is five basic heat treating processes: hardening, case hardening, annealing, normalizing, and tempering.
Heat treatment has a number of different techniques for changing the structure of the metal. Some of these techniques are quenching. Another method is annealing, where the material is heat-treated to become more workable. After heat treating is complete, hardness testing is performed to validate the level of surface hardness that was achieved through the heat treatment process.
