We provide our customers with quality services since 1960.


Tri-City Heat Treat provides a wide variety of services to our customers. There are five basic heat-treating processes: hardening, case hardening, annealing, normalizing, and tempering. Although each of these processes bring about different results in metal, all of them involve three basic important steps: heating, soaking, and cooling. Heating is the first step in a heat-treating process.

Below is a list of the services we are happy to provide to our customers. If you have a question about any of the services we present, feel free to fill out our contact form, and a member of our team will get back to you as soon as possible.
