So, serious question... when we see burned out husks like this. Why CAN'T we save the frame? I see people mentioning that the frame becomes fatigued, etc. But is that actually true?
When I send my control arms and steering knuckles to the machine shop... they basically put it in a kiln that strips off all the paint (burns it off), and even totally burns off the rust. It "floats" the metal a bit to the point where it restores the surface to perfectly clean metal. Is that not more or less what's happening here?
I realize of course that everything on the car is totally gone... I just wonder if the frame itself couldn't be re-used... like... if someone actually needed one.
At least no one is changing the heading to say, "Pontiac Fiero causes airport fire that burns out of control!"
When certain steels get red hot in a fire for a prolonged time it changes its properties. I am not a metallurgist but I believe the steel is both weakened and its dimensions change.

yes and no. you would need to put the whole car in an industrial powdercoating oven to temper after heating everything with a torch. now the fiero metal is pretty soft already so honestly if you straightened it and bolted in a few braces or a cage it would be totally fine. now it's a completely different story if the carpet or body was only slightly melted.
That rear decklid is looking rather grim. Looks like whomever butchered the decklid while prying it open also damaged the left taillight. Idiots abound.

I get the heat issue and its effect on the steel, but I think putting an Upper/Lower A arm into a furnace to remove the rust/oil/paint is a lot different then the very thin sheet metal that makes up the frame. I just cut the top off a T-Top car in my local Pick n Pull and I can tell you the frame is made up of very thin sheet metal that is boxed for strength. The sawzall cut right threw it like it was paper. I don't think I could cut threw an Upper/Lower A arm as easy. I would think that the heat would really mess up the thin metal of the frame. In this pic you can see that the strength comes from the boxing and over lapping of the sheet metal. Its thin but when all welded together its strong.
