The basic Cryogenic treatment (CT) consists in a gradual cooling of the component until the defined temperature, holding it for a given time (freezing time) and then progressively leading it back to the room temperature. The aim is to obtain an improvement of Mechanical properties, typically hardness and wear resistance, but in recent tests fatigue limit too, and to achieve an optimal ratio between conflicting properties, like hardness and toughness. The research about CT has been validated by the first results on machinery tools, which have shown remarkably enhancement in hardness and durability.
