looks like u admit also that there was more steel than just this one piece. they selected it for its unusual characteristice. thats odd considering the nist report states that none was recovered from wtc 7. u also state they just dont know what happened to that metel. then the nist needs to take a look at that and determine the cause so they can accomplish their stated goals.
your scrutiny isnt that great considering u are not for the nist having any steel to analyze from wtc 7.
it boils down to this, i would like to see the nist ananlyze some steel from wtc7 considering what the fema report said. u dont care if nist does.
When a large building collapses, a building that contains a significant quantity of drywall, you can be pretty sure that some of that drywall is going to get crushed into various size particles in the process. Do you disagree with that bit of common sense reasoning or do you imagine something completely different happened to it? If you imagine something else happened and that some of the drywall didn't get pulverized, please explain what that "something else" was.
I have no idea what you are implying by saying "the report states that the fire/debris weakened the structure." Are you claiming that you know for a fact that this corrosion happened before the structure collapsed? If so, how do you come to that conclusion?
And of course there was more steel than just this one piece. These were steel frame structures. There were hundreds of thousands of tons of steel in the debris field. As far as steel from WTC 7 being recovered, do you even bother to read the link you post?

C Introduction
Two structural steel members with unusual erosion patterns were observed in the WTC debris field. The first appeared to be from WTC 7 and the second from either WTC 1 or WTC 2. Samples were taken from these beams and labelled Sample 1 and Sample 2, respectively. A metallurgic examination was conducted.
Looks like you got your wish. Steel from WTC 7 apparently was recovered and analyzed. Happy now? Somewhere there's a lack of comunication between NIST and FEMA where NIST doesn't realize such steel was recovered even though they reported on it. Considering they're government entities, that's not surprising in the least.
Additionally, the FEMA report states
two pieces of steel were observed with these unusual characteristics. If the corrosion was caused by thermite/thermate, your base allegation that you still refuse to acknowledge is actually what you're implying, then hundreds of pieces should have been observed with those unusul characteristics. Nothing indicates that to be the case. To figure that out requires a bit of reasoning and critical thinking though, something CTs seem to be lacking. Either that or they simply refuse to consider any scenarios of common sense that destroy their fantasy.
The current NIST working collapse hypothesis for WTC 7
http://wtc.nist.gov/media/WTC7...ach_Summary12Dec06.pdf
An initial local failure occurred at the lower floors (below floor 13) of the building
due to fire and/or debris-induced structural damage of a critical column (the initiating event) which supported a large-span floor bay with an area of about 2,000 square feet;
the steel from wtc 7 was analyzed by fema man, not the nist. shit how many times do we have to go into this. u blame lack of communication??? and u still dont care if nist has steel to analyze from wtc 7??? that doesnt make sense to me.
as for steel samples to choose from-

INVENTORY OF RECOVERED STEEL
A total of 236 recovered pieces of WTC steel were cataloged; the great majority belonging to the towers,
WTC 1 and WTC 2. These samples represented a
quarter to half a percent of the 200,000 tons of
structural steel used in the construction of the two towers.
then in the same report-
STRUCTURAL STEEL IN WTC 7
No steel was recovered from WTC 7; however, construction-related documents describe the structural
steel as conventional 36 ksi, 42 ksi, and 50 ksi steels.
now answer this. u say the sulfur is from the drywall. well thats just not "sulfur" but calcium sulphate.
1. did the steel undergo those changes before it fell do to what the nist report states as "fire and/or debris-induced structural damage". then u have to explain to me how concentrated the hydrogen sulfide (from the burning of drywall) would have to be to cause that much damage on that steel sample??
2. if u think this happened on the ground, then u are going to have to explain how calcium sulfide (pieces of the drywall) became sulfur to actually attack the steel like that.
now i point out again the stated goals of the nist-
goal of the study was threefold: Determine mechanical properties of WTC structural steel, Determine the
quality of the steel and if design requirements were met, and Analyze the recovered steel to provide insight into
failure mechanisms to guide and/or validate models of building performance.
now why dont u want the nist to eval the steel from wtc 7 themselves independant of the fema report??
