Cryogenic
Metals like steel, iron, copper and aluminum are often heat treated to improve their physical properties. When metal is exposed to heat, it undergoes a chemical reaction in which its atoms expand. Normally, heat treatment is performed in conjunction with cooling. After the metal has been heated, it’s rapidly cooled to achieve more desirable properties like increased strength and durability. Cryogenic hardening, however, is a unique metal treatment process in which metal is intentionally exposed to extremely cold temperatures. Cryogenic hardening is a metal treatment process that’s characterized by the use of liquid nitrogen to freeze metal. While temperatures vary, it’s not uncommon for metal to reach -301 degrees Fahrenheit during this process. At cold temperatures such as this, the amount of martensite in the treated metal increases, resulting in some unique benefits that aren’t found in other treatment processes
