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.
