Cryogenic treatment is the ultra low temperature processing of materials to enhance their desired Metallurgical and Mechanical properties. Ultra cold temperatures are achieved using computer controls, a well-insulated treatment chamber and liquid nitrogen (LN2).
Applications on alloy steels, tool steels, brake discs, composites, cutting tools, plastics and race car engines.
Freezing the material at -300° f to modify the micro structure and improve the properties.
- A” Dry” Process
- A”one time “treatment
- A “through” treatment
- A treatment to improve properties – particularly the wear properties
HOW IT WORKS
The components being treated are held in a vacuum insulated chamber that is cooled below -300°F (-184°C) by vaporizing liquid nitrogen in a heat exchanger. Unlike cold treating, the process follows temperature vs. time profiles specific to the material being treated. It is a valid process for almost any metal, carbide, and some plastics. Deep cryogenic treatment affects the entire volume of the component being treated, so re-treating is not necessary when components wear or are sharpened.

BEST IN CLASS CRYO-PROCESSOR
The temperature vs. time cycle inside the chamber is programmed according to precise recipes, via a microprocessor based controller interface.
The heat exchanger technology eliminates the possibility of cold shocking the materials being treated by generating a homogenously cold gas atmosphere throughout the chamber. Heating elements in the machine provide a means of bringing the load back to room temperature
or above to add a tempering cycle. A paperless chart recorder provides a record of each cycle.
