Cryo treatment "group buy"

[JJacobs]

In about a month, I will be having all the parts of my car's transmission cryo treated. For that matter I'll probably throw in the ring and pinion and axle shafts. Thing is, that's far from filling up the machine, so to keep costs down..

Who else wants to get some parts in there? Gears and lockers, shafts, gun parts, you name it. I'm not really up on all the technical details such as exactly how much more strength to expect, you can google that. I do know that it takes about a week for the process to run. If you want in, shoot me a PM.

what's this type of thing cost? Obviously the more people the better. But I'm clueless.

Oh.... And can I just plop my whole xj in there. Lol

Oh.... And can I just plop my whole xj in there. Lol

HAHAHAHA right.

Would this work on front shafts? - alloys?

... im not a rocket scientist, but i always learned if you freeze metal, it becomes more brittle. how is this supposed to make it stronger?

i understand tempering, but this is just freezing

It increases wear resistance and strengthens parts

I wondered about embrittlement, so I spent about and hour reading. In a nutshell, the material's composition determines it's physical qualities. Cryo hardening finishes the chemical process that started when the steel was glowing-hot. The end result is a uniform, finer grain steel, with no internal stress from the processes that formed the part.

I was surprised to learn that cryo treatment is fairly common in industry:

Interesting offer JJacobs. Is there enough room for an old FE?

Seriously though, how much room, what are you guessing for a cost breakdown?

It's a big machine. Guys throw whole engine blocks in there all the time. Shouldn't be a problem getting anything from a vehicle in there. I believe it was around 4 bucks a pound, maybe less (or lots less) if we really load it up. Things do not need to be spotlessly clean, they recommend grease and wax paper to prevent condensation during the cool-down cycle.

Mike, it would benefit your front shafts for sure. I'm going to do my flywheel and pressure plate, gears and carrier and axle shafts along with the trans internals.

Doy ou think a U joint would do good? If so I will do my spares.

 

[time2getdirty]

Mike. you should just cut your jeep up into sections and have them cryofy it and then glue it back together and it will never break!

 

[time2getdirty]

You are already have way there!

Seems to me that the weakest part of a u-joint is the little bearings themselves. They're usually the first thing to fail that leads to the larger fail... Dunno it'd be worth tearing down a u-joint and all it's little rollers, and finding a way to cryo them...... :dunno:

I never have broken a U Joint in my driveshaft yet, the straps let go first. I think it would cool to say my u joints have been croyfied.
