Cryogenic hardening — is a cryogenic heat treating process where the material is cooled to approximately −185 °C (−301 °F), usually using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels, provided their composition and … Wikipedia
Cryogenics — For cryopreservation/resuscitation, see Cryonics. For the band, see Cryogenic (band). In physics, cryogenics is the study of the production of very low temperature (below −150 °C, −238 °F or 123 K) and the behavior of materials at those… … Wikipedia
