Cryogenic liquids are materials with boiling points of less than –73 °C (–100 °F). . What are Cryogenics?. Cryogen Background . When stored and used properly, cryogens are safe.. If stored improperly or misused, cryogen can be dangerous and even kill you.. Introduction. Most mechanical devices such as fans, pumps, etc. produce vibration.. Vibration is easily transmitted through solid materials and may ‘appear’ elsewhere producing troublesome vibration and/or noise.. What is cryogenic heat treatment?. Cryogenic heat treatment is the ultra low temperature processing of materials to enhance their desired metallurgical and structural properties. The temperature is about -196°C or 77°K.
