Hardening and tempering in vacuum or gas Quantum G
Quantum G series vacuum furnaces
Quantum vacuum and gas quenching and tempering
Vacuum and gas hardening and tempering are thermal treatment processes for materials to improve their mechanical and physical properties, such as hardness, strength or wear resistance. Quantum G Technology offers advanced solutions for these processes, based on controlled vacuum or gas atmosphere conditions.
Vacuum quenching
Vacuum hardening involves heating materials to austenitizing temperatures in a vacuum atmosphere, followed by rapid cooling (e.g., by a stream of inert gas) to achieve the required hardness and structure.

Vacuum hardening process:
Vacuum generation
Heating
Cooling
- No oxidation or scale formation on the surface of the material.
- High uniformity of machining due to precise parameter control.
- Ability to harden complex geometries.
- Minimizing thermal stresses.
- Cutting and forming tools.
- Aerospace Components.
- Precision machine components (e.g., shafts, gears).
- Quenching in gas (e.g., in nitrogen)
- Gas quenching is an alternative to classical cooling in oil, where the cooling medium is gas at high pressure. The process is particularly useful for steels with higher hardenability.

Tempering is the process of heating the material after quenching to a temperature of 150 to 700°C, depending on the required mechanical properties. Its purpose is to reduce brittleness and give the material the required strength and ductility.
How does vacuum tempering work?
Process in a vacuum
Treatment is carried out in a vacuum oven, eliminating the risk of surface oxidation.
Temperature control
The process is strictly controlled to achieve uniform mechanical properties.
Application of gas
After tempering, cooling in an inert gas atmosphere is possible.
