Grain Growth due to Overheating???

*** You're right Mr. Perkins. I thought that it could be etched in stainless steel that 5160 and 52100 are NOT forgiving steels but looks like he did not say that with confidence.:D Anyway, thanks so kindly for this very informative response of yours and specially for the link to that book of Prof. Verhoeven. The forgiveness though that I'm looking for, for lets say 5160 and 52100(to be specific) is their ability to get back to their normal grain sizes by annealing, or normalizing if or when, grain growth is inadvertently induced into them. Would appreciate your words of wisdom about this curiousity. Thanks again.:)

I would say that you shouldn't have any trouble with grain size if you do a couple annealing cycles at close to the critical temperature and don't drastically overshoot the critical temperature at the heat-and-quench stage.

***Thank you much Mr. Perkins. I realize the importance of not allowing grain growth to occur but I was just wondering if they are reversible that's why the original question was asked. Have a nice day now.
