  • Deep cryogenic tempering process based on flashing liquid nitrogen through a dispersal system
    Patent number: 5865913
    Abstract: A method for treating firearm barrels and components to achieve an end result of increased accuracy and extended barrel life. The method involves placing the firearm barrels and components into cryogenic processing and heat treating equipment. The processing temperature is then significantly lowered to about -300 F. and maintained for a predetermined time. The processing temperature is then raised back to ambient temperature. After achieving ambient temperature the processing temperature is then raised to about +300 F. and maintained for a predetermined time. Finally the processing temperature is lowered back to ambient temperature.
