Following heat treating cycles, many industries are now requiring Cold and Cryogenic (Deep Freezing) treatments be done in order to increase hardness and wear resistance and to further reduce metal fatigue.
Cryogenic treatments are usually done immediately following quenching and before any tempering is done. It does increase the hardness and wear resistance and reduces metal fatigue, but it may also increase the chances of cracking during the process. This is because cryogenic treatments are really just an extension of the quenching process.
Cryogenics is often used for gears, bearings, tools and other items that require a higher wear resistance and durability. However, it is usually only effective in metals in which more than 10% austenite is retained after quenching, such as high-carbon or high-alloy steels.
