Heat/cryo treating timeframes
This seemed the best place for this.
This is less about the benefits of heat and/or cryo treating, rather the timeframes in which to do them.
Based on what I’ve read so far, and by no means is it extensive, you have heat treating on one side, cryo on the other. Meaning they’re somewhat mutually exclusive processes where one company may do one, and one company the other, but rarely the same from what I can tell.
With respect to cryo treatments, the part may get heated to ~300c before being cooled, possibly back up to 300, then to room temp whereas heat treating is up to 900.
I’d be curious to know whether there is any benefit to the process doing it in one go.
As an example, you can get e-shafts from Precision that are heat treated. This would be shipped to the US where I could get it cryo treated. I suppose I could forego the heat treatment and do it locally, speeding up the process, but is it all moot?

From what i read on wikipedia (https://en.wikipedia.org/wiki/Cryogenic_hardening) and rememebr from our material science at the uni, heat treatment and cryo does sort of the same thing.
I would call up the cryo guys and ask what type of heat treatment (if any) they require the part to be before they get it.

I'll try to weigh in based on how I read your question. The two processes can absolutely be done independently of each other, but they are not contradictory. Performing cryo treatment after heat treatment will not cancel out the benefits of heat treatment.
As for having the services performed, it just depends on the capability of the shop. I have my transmission at Liberty's Gears being built right now and they offer both services (plus more) in house!

Thanks, and fair enough. It was a bit wordy for what I was trying to convey. I wasn't concerned about the processes being detrimental to one another. Rather whether there was any benefit to doing the process in a single process...normal heat treatment directly into cryo.
But I suppose the answer is good enough for me.
Thanks!

Hmm, I'm fairly certain that the parts should be brought back to a normalized temperature and inspected after any treatment processes like that.
I think that trying to immediately go from one extreme to the other would be hard on the machinery/workers and perhsps detrimental to the materials.
