High alloy steels can be heat treated without cryo as long as the austenitizing temperature isn't too high. See the chart below on AEB-L, for example. However, higher hardness is possible when using cryo. ... Even experienced knifemakers can provide poor heat treating advice so I would generally recommend following the datasheet unless you ...

Heat Treating Overview Heat treating, as the name implies, is a series of treatments in which heat is used to alter the properties of a metal or alloy. Because time at temperature is also important, heat treatment can be further defined as a series of time-temperature treat-ments. Heat treatments are used for a variety of purposes, the
