I dunno. Tend to agree with Bill on this. From my classes in material
science a metal (liquid) only changes its properties based on how long
it's kept at how high (not low) a temperature and how quickly you quench it.

When I first saw that site it rang my -------- detector loud enough to wake
the dead in five states.

Somewhere out there there is a study on cryogenics vs non and they show
no difference in wear at all. If I find that link I'll post it.

Re: 98 TJ brakes - rotors & pads
 

All that fancy tempering and annealing stuff must not work either because
the metal is never returned to the molten state. ;-) Think of it as a
thermal stress relief and additional annealing cycle. Cryogenic treatment
does work and in many applications provides a marked improvement in material
durability. I would not pay twice as much for a rotor since I do not believe
it will last twice as long as an untreated one, but this outfit:

seems to have a pretty good handle on the process and their prices are not
outrageous.

Molten, was a bad choice of words, as in forging no heat is added
yet the steel turns cherry red.

Hi Doug,
Interesting study at:
http://www.bso.uiuc.edu/~chillar/Cry...ntofMetals.pdf Tests
showed cryogenically treated of cast Iron load capacity got poorer by
23.1%, but increased the abrasion resistance of that specimen by 35.7%
