CRYO PROCESSING ADVANTAGES

BEFORE

 -- Transforms almost all soft retained austenite to hard martensite.

-- Forms micro-fine carbide fillers to enhance large carbide structures.

-- Creates a denser molecular structure.  Simply stated, your “edge” has more “edge”.

 

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.

 

 

AFTER

Cryo treatment can decrease the likelihood of premature failure and relieve much of the residual stress. Grain boundaries are where stress and defects are most likely to be.  Inherent material defects may cause a material to fail prematurely. Applications include gears, shafts, turbine blades, and other critical parts.  Micro-hardness* readings were much more consistent in the cryo treated specimens.  In the untreated specimens the hardness readings varied from place to place within the specimens.
