Vacuum Heat Treatment of Fasteners - vacaero

The most popular method of quenching used for hardening in vacuum furnaces is inert gas pressure quenching used at pressures of 2 – 20 bar. Nitrogen and argon are the most common quenching gases. Cooling in argon produces the slowest heat transfer rates, followed by nitrogen, then helium and finally hydrogen....<<more>>
