I am interested in hearing from anyone who has had experience 
in "Dry, controlled" Cryogenic processing on metals to extend 
tool life. The dry process is defined by the fact that the part 
is not immursed in liquid nitrogen and that the process is 
controlled over a period of about 30 hours. 

We have found that the process works great on some applications 
and marginal on others. 

Thank you in advance for any assistance or information.
