IPSEN introduced high pressure gas quench to the vacuum furnace in 1970s and that made vacuum furnace heat treatment explode in popularity as from then on the benefits of vacuum heat treatment become accessible to a wider variety of metal grades and parts geometry. So let’s review the evolution and what affect gas quench performance.

In 1970s almost 90% of hot zones were all metal, by now that market share reduced to 20%. The shift has happened because graphite hot zone is more economical, more forgiving to operation mistakes and more energy efficient than metal hot zone. It is good enough for most vacuum processing applications. However, all metal hot…

Good choice for nitriding in vacuum is a pre-evacuated hot walled retort furnace that offers excellent solution for many heat treatment application, especially case hardening. It is more cost effective than a vacuum cold walled gas quenching furnace, but of course has also drawbacks. Let’s learn more about it …
