Cryogenic Tempering Machine
Manufacturer: 300 Below Inc. (USA)
This large tank uses LN2 (Liquid Nitrogen) to freeze/soak steel & metal to -300F for a period of 24+ hours, then heat tempers for a further approx 29 hours in one single process without having to load the items into an oven after the freezing cycle. The machine can also just freeze or heat temper.
Comes with state-of-the-art Watt controller which records temperature at each minute of the process. A full Cryo Tempering process takes 53 hours.
It does NOT come with an LN2 tank – you will need to arrange this separately.
