cryo treat your parts
 

has anyone tried the cryogenic freezing tech. on their parts yet? prices are reasonable. check it out, thought you might want to try:www.deepfreezecryo.com let me what ya'll think good or gimick. i do know some people that have had rifle barrels froze. they have had no problems.

i read a zc buildup where he cryo treated his pistons. he put in 89 integra pistons i think. he was running non turbo but a 100 shot of nitrous i think, he blew up the motor from a problem with the nitrous, but i think the cryo treatment worked fine other than that.......i cant remember the site though.

yeah that was the guy from Quickhonda.net

Hope im not the only one, but what the hell does the freezing do? Does it harden the metal or something?

Re:cryo treat your parts
 

DON'T KNOW, BUT I HOPED I COULD ENUFF FEEDBACK ABOUT IT FROM YOU GUYS

Here's a link I saved a while back.

they cool it down to like -400 or something crazy. then it is warmed up very slowly allowing for the molecules to line up and make the part harder.

much like a mineral.

Thats crazy.

The hardness does not change, but the amount of retained austenite is supposed to be reduced. This is what affects the wear rate of materials in friction.

I have done a lot of research in cryo treatment, and have read hundreds of pages of hoo-haw about it, and it is still a little bit of a mystery on some things.

From the perspective of steel parts, it is proven to reduce the retained austenite, as it is simply an extension of the age hardening portion of the heat treating process. But the mysteries still lie in the claims that aluminum benefits from the process, or other materials. They say golf balls drive farther after cryo treatment, and that it is not a legal thing to do in competition. There is no way that anyone could prove that the treatment was done though, on anything.

I am currently testing cryo treated brake rotors on my car, so far so good. It is too early to tell though, but I have two track days on the rotors and they are still like new. I have blasted through a set of rotors in one day before when the brake pads overheated. :o

I thought that cyro treating brings the temps way down and therefore brings the molecules closer together adding strength.

Re:cryo treat your parts
 

I thought this was just for freezing dr. evil and austin powers?

But seriously... think about it, freezing the metal holds the molecules more closely and warming it up loosens them. I guess I don't see any logical explanation to how this could improve the strength of the piston, or anything for that matter... As once you get back to 'operating' temperatures any benefits of cold would be lost?

I understand a slow unthawing might help with something, but just doesnt seem plausible to me.

Re:cryo treat your parts
 

I understand what you are saying, but you need to think about cryo treatment as actually an extension of the heat treating process, not just a change of size in things in relation to temperature.

In the heat treatment process, the material is heated up to a range where the molecular structure changes, and the method used to cool the parts is what determines the final molecular structure. In steels, martensite is the preferred structure, and is very strong, and austenite is unwanted material between the martensite. It is called the aging process, and the austenite "precipitates" out of the structure. There is a small amount retained though when the structure reaches room temp. The cryo process continues this precipitation if it is done, and even more has been proven to be removed by going "deep", which is how they refer to a liquid soak at -320. Most only go to -300.

The biggest uses for cryo treatment are in industry, not really motorsports. They treat things like drill bits, and cutting tools, and have proven that they can last about 300% longer before replacement/resharpening.

COOL !!!! no pun intended ;)

Re:cryo treat your parts
 

hmmm... would this be kind of like the way that the japanese used to fold their katanas over and over and let it cool outside instead of in water? (to work out the impurities I know)? Except more hi-tech...

Re:cryo treat your parts
 

cool.

i just got owned! ;D
