stainless steel ID shrink in heat treat? 420

[fettersp]

I have a part that has a diameter of 4 inches, 1.5 inches long and with an ID that's supposed to be 2.626 inches. the current ID is 5 grand over. I'm just curious if heat treat will be able to shrink the ID at least 3 grand. the steel is 420 stainless. I could just scrap it but would be a waste of 328 dollars if it can be saved.

Not likely. But if it doesn't cost much to treat have them run it.
