Cryogenic Treatment of Materials

(OP)
Is there a significant difference in the final wear properties of tool steel materials treated in liquid vs vapour?

RE: Cryogenic Treatment of Materials

Yes.  The rate of decrease of temperature in true cryogenic processing should be slow.  Dunking the part in liquid creates a very fast decrease in temperature which causes micro cracks or even macro cracks.  Research out of Russia indicates that metals treated by dunking have only a ten percent chance of increased wear resistance.
