Lets Talk Rotors: Cryo-treating

cv129

Reviving an old thread. I was researching on rotors and I found some interesting read on cryo treatment

cryogenic rotors - Page 2 - Rennlist Discussion Forums

cryo-treated rotors = snake oil! - NASIOC

Cryogenic Rotors: Good or Snake Oil? - Pelican Parts Technical BBS

I was also reading on RB rotors, they heat treated their rotors but do not use cryo treatment.

Seems like results vary. Hope we have some chemists/engineer here that can chime in.

Interesting reading. People with degrees calling it snake oil. I've had ring and pinions done years ago. Was to help stop breakage of the teeth. Still broke them tho.

First, saying they "heat treat" is too generic to mean anything. There's so many heat treating processes, without knowing which one specifically is used is worthless.

Secondly, when done right, cryo-treating absolutely can be useful. Cryo-treating is used in more places that brake rotors. Numerous companies that are doing heat-treating (typically carburizing) have deep-freezers for cryo-treating.

Unfortunately, while I might design heat treat furnaces, I'm no metallurgist so I can't tell you what the chemistry behind cryo-treating is.
