Our vacuum tempering furnaces are designed to perform precise tempering cycles under high-vacuum or protective gas conditions.

By effectively eliminating oxygen and reactive gases during the heating process, the furnace helps prevent surface oxidation, decarburization, and discoloration, making it especially suitable for components with high surface finish requirements after quenching.

The system is ideal for stress relief after hardening, toughness improvement, hardness stabilization, and dimensional correction of precision parts.

The equipment can be configured with nickel-chromium or molybdenum heating chambers, depending on operating temperature, material compatibility, and process requirements.

For applications with large batch loads and lower operating temperatures, optional convection heating systems can be integrated to improve heating speed and temperature uniformity.
