Vacuum Hardening Quenching Pressure

The adjusted positive pressure of an inert gas (e.g., nitrogen) during gas quenching in vacuum furnaces. It decisively determines the cooling rate and thus the achievable surface hardness.

The quench pressure in the vacuum furnace determines how fast the gas removes heat. More pressure means faster cooling, less pressure means slower cooling. Adjust the pressure to the material and the desired hardness – too fast makes the structure hard and crack-prone, too slow makes it too soft. Run the cooling so you get a clean, crack-free result, and watch the temperature curve.
