Cleanliness, control, and safety – some of the reasons you may want to consider vacuum heat treating for your next project.

Why?

Heat-treating in the presence of air can cause oxidation problems that are virtually eliminated by performing the operation in a vacuum atmosphere. It gives the ability to precisely control heat-up and quench rates, minimizing heat-induced distortion. The results are clean, shiny parts which require comparatively little post-treatment finishing and cleaning.

In addition, Vacuum Heat Treating allows you to change cooling rates easily, even within a single cycle, thereby enabling gas-quenching operations that can produce full hardness in steels. Contrast that with liquid quenching, where the cooling rate is fixed and multiple baths are required to achieve the same results as a single gas-quenching operation.

Finally, Vacuum Heat Treating does not produce toxic or combustible waste gases, making it safer and more environmentally friendly than many liquid-quenching processes.
