Cryogenic hardening is a cryogenic treatment process where the material is cooled to approximately −185 °C (−301 °F), typically using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels , provided their composition and prior heat treatment are such that they retain some austenite at room temperature.
Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...
The cryogenic treatment process was invented by Ed Busch (CryoTech) in Detroit, Michigan in 1966, inspired by NASA research, which later merged with 300 Below, Inc. in 2000 to become the world's largest and oldest commercial cryogenic processing company after Peter Paulin of Decatur, IL collaborated with process control engineers to invent the world's first computer-controlled "dry" cryogenic ...

Cryoconservation of animal genetic resources is a strategy wherein samples of animal genetic materials are preserved cryogenically. [ 1 ] Animal genetic resources, as defined by the Food and Agriculture Organization of the United Nations, are "those animal species that are used, or may be used, for the production of food and agriculture, and ...
Technicians preparing a body for cryopreservation in 1985. Cryonics (from Greek: κρύος kryos, meaning "cold") is the low-temperature freezing (usually at −196 °C or −320.8 °F or 77.1 K) and storage of human remains in the hope that resurrection may be possible in the future.
A feral horse captured by the Bureau of Land Management and freeze branded using the alpha-angle system.From left to right the brand says the horse is registered to the federal government, was born in the year 2000 and carries the registration number 012790, indicating that it was branded at a BLM facility in Oregon.
Cryonics (often mistakenly called "cryogenics") is the practice of cryopreserving humans or animals that can no longer be sustained by contemporary medicine until resuscitation may be possible in the future. The process is not currently reversible, and by law can only be performed on humans after legal death.
