Post Strenghtening parts with cryo or heat?

I was curious if anybody out there knew enough about treating parts to increase strength? Reason is I was curious if there is a benifit of cryogenic hardening or heat treating drivetrain parts? Is one superior to the other? They seem to cost the same either way so price doesn't seem to be a deciding factor. I need to know since I will end up having to have one of them performed on the axles and rear diff in a Pulsar. I tried a search about this and it hasn't been covered yet so I thought now would be a good time to ask.

Check out http://www.frozenrotors.com/ and they have a complete description. Basically, metal has weak spots and strong spots. By heating/cooling and bringing back to room temperature you break down the bonds and everything kind of equalizes to make one strength all the way through.

Rember when you harden a part it also becomes more brittle. you have to find a happy medium between the two. If you have specific questions about specific parts E-mail me and I will try to help.

Thumbs up

My mechanic just had his small block Chevy cryo'd and his connecting rods shot-peened. He's running 16:1, all natural. Chevy 350 w/custom intake manifold, Oldsmobile 350 tranny, and ford rear end. Street legal? It has a license plate. Tube chassis Chevy Nova, 8 seconds. All throttle, no bottle.

When I was in college we did some S.E.M. and T.E.M. work on metals that had been cyrogenically treated. What was noticed was a more uniform pattern in the crystalline lattice of the materials and a more uniform dispersion of the silicon. Its been about three or four years. My memory is relatively hazy on the exact findings. However, what would really back up the findings are stress tests, etc.

Some of your drivetrain parts are already treated for hardness. I know the axleshafts are for example. If I think of it tomorrow I'll post some pics of some spare shafts I have hanging around... it's relatively easy to see.
