A gas cooker flame is around 800C. These flames regularly come into contact

The cookware never gets as hot as the flame, because the heat
gets conducted away. And how would you know if it has lost half
its strength?

You can hold a pin in a candle flame and get it to glow red and
loose stiffness.

The steel used in the construction of the WTCs was a special steel with a
higher melting point than ordinary steel somewhere around 3000C.

Not even close. Let's see you try to cite that one to a
non-kook source. (Even kook sites are saying 2800 degrees
Fahrenheit or less, which is 1538C.)

Some forms
of steel actually gets stronger when heated. Its possible 650C would have no
affect whatsoever on the strength of some forms of steel.

So how come they put fireproofing foam over it? Why does it
loose its fire rating if the foam gets removed?

Indeed if those
sort of temperatures adversely affected steel to the extent you claim it
would not be possible to run a IC engine on Gasoline/Petroleum without the
cylinder block imploding.

Let's listen to some people who actually know what they're
they're talking about. Here's how hot room fires can get:

Here's Matthys Levy, author of /Why Buildings Fall Down/,
on the steel softening in the WTC towers:

    So that fire caused the steel to soften up. The columns
    in the interior of the core began to soften, buckle, fail.
    And I saw that the building had really a good chance of
    collapsing at that point. [/Nova/ "Why the Towers Fell";

Amazing what one can learn by bothering to check.
