 Advantages
- Increase resistance to abrasive wear
- Requires only one permanent treatment
- Changes the entire grain structure of the metal, not just the surfaces
- Refinishing or regrinds do not affect permanent improvements
- Eliminates thermal shock through a dry, computer controlled process
- Transforms most retained austenite to hard martensite
- Forms micro-fine carbide fillers to enhance carbide structures
- Increases durability and wear life
- Decreases residual stresses in tool steels
- Decreases brittleness
- Increases tensile strength, toughness and stability
- Relaxes internal stresses
- Works on new or used tools
- Reduced down time, less maintenance and higher productivity
- Deep cryo processing is compatible with other treatments (TiN, Chrome, Teflon etc.)
- High alloy steel cutting tools stay sharper longer, fewer micro-cracks, less chipping
- Results in the orderly arrangement of crystals, increases internal bonding energy, and achieves a structural balance throughout the mass of the material

The grain structure changes in cryo treated materials were very significant.
Results of microanalysis were:
- 50%-75% decrease in grain size in treated specimens
- Much more uniform distribution of carbon
- Alleviation of grain boundaries
