Fire damaged frame

I've just inherited an old steel Dawes road frame off a mate. I have bits ready to start sticking on it for the latest project. Only problem is, it's been in a fire and clearly taken a bit of a pasting. Most of the paint is gone but it's been checked out for straightness at a bike shop and fine in that respect. The bottom bracket still fits fine - no warping there. There's no apparent reason why it wouldn't look good as new with a powder coat - or make the super-unstealable pub/polo bike without.

So is it safe?
I guess I know what people are going say. It's not a valuable frame, so why risk it when I can get a new one. But it's right there in front of me and I'm impatient. Am I destined for an early grave if I use it?

i reckon it'll be ok.

Heat treated steel is stronger.

I doubt if the heat it was exposed to was anything like what it had when it was brazed together, so off you go and play (nicely now!)....no upsetting those motorists who think they own the road...they don't like being wrong, the ego can't take it!

during rebuilding a fire damaged house last year, we found a live hand gun hidden in the cavity of the first floor wall...it had melted, bullets and all! the heat can be more than you'd think. if the frame is straight and true then it clearly wasn't a hot enough fire

Heat treated steel is stronger.

nope, it's harder.

but as has been said, if it can survive brazing it can survive a fire.

Cheers all, just the kind of positive response I needed to dream up the new build and get me through the first day back at work
