Tempering A Tank With A Burnout To Minimize Door Spring???

[Q-Dat]

I was given a suggestion to try this. Someone told me that if I get the tank really hot with a burnout(which I will need to do at some point anyway) and just let it cool slowly that it will temper the steel to some extent and possibly eliminate door spring, but at the very least it should make it easier to correct if it does still happen.

Anybody heard of doing this?

There is a section of this statement that describes QUENCHING tempered steel and how it can relieve internal stresses in the metal.

For some reason this link is not posting correctly but when it comes up...it says. " DID YOU MEAN "

Click on that and the page comes up

So theoretically, I might be able to take my weed burner torch and an infrared thermometer and go all over the tank making sure that I have heated it to the right temps.

The last time I used that theory, it failed miserably.... But, what do you have to lose...go for it. One likely hood is that un-even heating may simply shift stress points elsewhere in the tank?
