I would depend on the temp. The exhaust caused some discoloration to the chrome on my exhaust tips.
I do not know at what temperature chrome will turn blue but I would be cautious using an open flame or a hi-temp heat gun.
Best, Ben

I have recently been researching stripping and restoring cast iron cookware and one of the methods presented was building a large fire and letting it burn down until you have a nice pile of hot coals. you then bury the skillet in the hot coals and let sit overnight. Once cooled off, pull the skillet out in the morning and wash, dry and begin the seasoning process.

If fire is good for removing a dork disk, why wouldn't it work to strip paint?

Otherwise I personally wouldn't trust that frame, but it might be fine for a neighborhood knock-about or or grocery-getter that doesn't get much stress placed on it. I wouldn't get too far from home with it.

One thing I have discovered of late - if you want to remove powder-coat - fire is definitely the way to go!

when I'm fixing a frame I burn the paint off with my torch in the affected area and then mechanically remove what's left. It really doesn't heat up the frame that much.
Probably why my asthma never gets better.

Just paint it and ride it . If it makes some weird creaking noises then you worry, until then go for it.

i have a chrome fork i had dechromed and some canti bosses brazed on. the base nickel plating is still intact and only oxidation is where the plating was ground off to braze the bosses. iow's, even with all that heat being centralized and the plating surrounding the bare areas, the plating looks untarnished. but, it's probably gonna fail because it got hot
