Still no source for that claim?

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.)

That's the melting point of Iron, steel is an alloy and has different
poperties to Iron.

That is correct. Steel has a *lower* melting point, around
1370 degree C.

Structural steel can have a higher melting point than this
but still lower than iron:
