What Is Vacuum Hardening?

High-Precision, Clean Heat Treatment

Vacuum hardening is a heat treatment process carried out in a specially designed vacuum furnace. In this process, steel parts are heated to a specific temperature (called austenitizing), held for a precise duration, and then cooled (quenched) using high-pressure inert gas.

The big advantage? This process takes place in a completely controlled, oxygen-free environment, so your components come out:

• Hard and wear-resistant
• Bright and clean (no scale, oxidation, or decarburization)
• Dimensionally accurate with minimal distortion

This makes vacuum hardening the go-to choice for parts that need to meet tight tolerances and perform under stress.
