Cryogenic treatment is an inexpensive supplementary process to conventional heat treatment, which improves the tribological properties of steels. A study has been made on the effect of cryogenic treatment on En 31 steels done at different stages of heat treatment. It is observed that through cryogenic treatment the wear can …

The cryogenic quench itself is performed primarily in two ways: shallow and deep treatments. In the shallow treatment, the blade steel is brought to approximately -112°F for five hours, while in the deep treatment it is reduced to roughly -321°F for about 35 hours. This is most often accomplished through immersion in liquid nitrogen. "The ...
