Ok,A very knowledgable forum member put me onto some sites regarding cryo..
This is a rats nest for the uninitiated...
Basically a heat treated component which has not been thoroughly heat treated(The quality of the process was not controlled and the process did not run its proper course..)can PERHAPS benefit from cryo after the fact.
If the heat treat process was only 70% successfull and you cryo`d it afterwards,it MIGHT take the process to 75% effectivness..Its got to do with the state of the materials before treating and after..
The 75% figure could be anything,no one knows(this is the way I figure the ramblings)it could be more ,it could be less..
The application apparently does not benefit from the process..It is only the base material that MAYBE benefits..
Cryo will do nothing for splines for example,as the weak point with splines are where they stop and the rest of the shaft continues..
Hell,I hope Im not talikng crap here..but this is what I read into it..
We realy need an engineer in metalurgy to help here..and then he needs to have cruo experiencs..
Different materials can benefit to differing amounts and a load of other stuff..
Way beyond me Im afraid..
Ill do some more homework and see what I can come up with..
(What Im actually saying is Ill get the enginr to write a piece for us and then claim cudos for doing the job myself!!!)
