Gas Quenching

Gas quenching is an environmentally friendly alternative to oil or salt bath quenching applications.
Associated with low-pressure processes such as carburizing, gas quenching offers better control of distortion and limits post operations such as rectification.
Primarily developed for high performance materials, gas quenching can be performed with nitrogen, or sometimes helium.
More recently, the development of vacuum carburizing applications in the automotive industry has required high-pressure gas quenching furnaces with pressure up to 20 bars.




Our ALNAT™ solutions include gas supply, related gas handling equipment, and a range of services related to the generation, use and control of atmospheres in industrial heat processing furnaces.
