low heat for a long time can do as much damage as much higher heat for a much lower time period.
That's the first I've heard of that, no offense but I think that would need a bit of qualification. My understanding is that any changes occur at a certain temperature and time doesn't effect the changes, that is, 375 degrees held for ten years will effect the temper as much and no more than 375 degrees for five minutes. If I'm wrong my whole understanding of heat treatment is going to have to be reexamined.

Thank you sir for your service. May God bless the troops!
