High-Pressure Gas vs. Oil Quenching

Vacuum furnace technology has advanced quite a bit throughout the years. While conventional oil quenching method still produces great results, the newer high-pressure gas technique is the preferred method for many metallurgists. One big advantage to using high-pressure gas is that it treats material in a much more uniform way. While all forms of heat treating will cause some level of distortion, we typically see 50-75% less distortion with gas than with oil quenching.
