G3000 Gray Iron - School me on it

G3000 Gray Iron - School me on it

(OP)
We're going to manufacture some brake rotors here for the owners personal race car. Ive determined we're going to use G3000 cast grey iron per the SAE standard for the alloy. I have some questions regarding stress relieving.

From what I understand - you stress relieve the iron prior to machining correct?

Any other processes I should do to brake rotors?

What about cryogen? Ive heard its great and Ive heard it doesnt make a pinch of crap difference.

thanks for your help

At the risk of starting another cryo war--don't bother with cryogenic treatment on the rotors you will be making.

I appreciate the response - but I already had that.

Swall - thanks for the input but I need something more than just "dont bother with it". Got some experience or justification?

RE: G3000 Gray Iron - School me on it

OEM rotors are not cryo treated. Rotors from Autozone, NAPA and other aftermarket OEM type rotors are not cryo treated. If you are making a specialty product, you could consider the profit enhancing opportunities of cryo treatment.
