Aerospace Controlled Atmosphere Heat Treating

NADCAP-approved processes for durable, high-performance aerospace components.

Aerospace Controlled Atmosphere Processing

Using our atmosphere furnace, we can control nitrogen and argon. These furnaces are used for annealing, hardening, tempering, normalizing, and stress relieving.

Hy-Vac’s stress relieving furnaces reduce stress resulting from forming, rolling, machining, or welding — first heating components to specified temperature levels, then cooling them at slower rates. This procedure can be incorporated into the engineering process for large or intricate parts.

Below are the most commonly processed materials and specifications. Please contact us for inquiries about any not featured on this list.
