Why did WTC steel show evidence of rapid steel sulfidation corrosion, never seen before in building fires?

Question

Analysis of the WTC steel revealed this:

"Evidence of a severe high temperature corrosion attack on the steel, including oxidation and sulfidation with subsequent intergranular melting, was readily visible in the near-surface microstructure...The thinning of the steel occurred by high temperature corrosion due to a combination of oxidation and sulfidation.
The unusual thinning of the member is most likely due to an attack of the steel by grain boundary penetration of sulfur forming sulfides that contain both iron and copper.

liquid eutectic mixture containing primarily iron, oxygen, and sulfur formed during this hot corrosion attack on the steel.

The severe corrosion and subsequent erosion of Samples 1 and 2 are a very unusual event. No clear explanation for the source of the sulfur has been identified."

This reaction had never before been seen following a building fire. So where did the sulphur come from? Well, guess what contains sulphur? You guessed it, thermate.

And guess what uses an oxidation process in igniting the thermite-sulphur compound?

You guessed it. Thermate!

Umm duh, but we have PLENTY of instances where other buildings BURNED.

And rapid steel sulfidation corrosion has NEVER been observed in ANY of them.

FEMA and NIST were at a loss to explain WHERE the sulphur came from.

But hey, guess what contains sulphur and is oxidized when it ignites?

THERMATE! WHAT A SHOCK!

The point was not all destructive chemical compounds use an oxidation process in their reaction. Perhaps I should have used a word other than "ignite".

Answer 1

It wasn't a building fire. A PLANE CRASHED INTO IT.

Compare it to instances of other comparable planes hitting other comparable buildings.

Oh, that's right - YOU CAN'T! IT NEVER HAPPENED BEFORE SO WE DON'T KNOW WHAT "NORMAL" WOULD BE IN THAT SITUATION!

Answer 2

Do you think that it would have happened if there had not been a fire. Remember Twin Towers was designed in the 60's and the steel made in the late 60's under different federal guidelines at the time, the way steel was made in the late sixties ad different compounds than today because technology has evolved. So there is no mystery or conspiracy here.

Answer 3

Just so you know, FIRE IS OXIDATION. So EVERYTHING that contains sulfur and burns is being oxidized you nutjob, not just thermate. Matches contain sulfur and oxidize. Maybe George bush used a match to take down the WTC. Next time make sure you are using terms you actually understand before you issue your amazing conspiracy theories.

Answer 4

Since we have no other instance similar to this to compare it to, there is no reason to assume that this is unusual. Is there something in the jet fuel that could cause this? How about something in other materials within the building? Does the extreme heat of the fire (hot enough to weaken steel) play any role in a reaction to cause this effect? There is far too little evidence to come to any rational and scientific conclusion.

Answer 5

Building fires release Sulfur Dioxide.

Jet Fuel also releases Sulfur Dioxide because it contains sulfur and mercaptans.

Answer 6

Guess what else contains sulphur: Gypsum.

Answer 7

Like you actually understand a single word of that analysis.

Answer 8

We'd never had a plane crash into a building like that before either.

Unfortunately all investigations into the WTC collapse have been blocked.

It's almost enough to make you think there is some kind of conspiracy...

Answer 9

Ok Bush did it, He hit it with a plastic hammer!

Answer 10

Here you go.
