FACTS:
Melting temperature for steel (iron + carbon) is exactly 1532 C.
Air fires cannot burn hotter than 600 C even in very strong winds, simply because of lack of oxygen.
If the only source of oxygen for a jet fuel fire, is open air, stationary air, then the typical flame temperature is usually around 233 C to 250 C.
Fahrenheit 451 F = 233 C.
Air fires do NOTHING to steel.
They don't even weaken steel one bit.
Steel starts to lose a little bit of strength at around 300 C. And drops to about half top strength at about 650 C. Steel still has significant high strength even at 1100 C. And will behave like rubbery, bendable, soft chewing gum, all the way up to 1532 C - because it remains as a SOLID until 1532 C, the melting temperature.
The melting temperature of Aluminium is around 550 C.
Ever noticed your steel motorbike engine parts falling apart or collapsing due to fuel combustions?
or aluminium frying pans & steel pots melting in a fire? why not?
