"7a. How could the steel have melted if the fires in the WTC towers weren’t hot enough to do so?

[...]

In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, Figure 6-36)."

According to Greg Fuchek, vice president of a company that supplied computer equipment used to identify human remains at Ground Zero: "Sometimes when a worker would pull a steel beam from the wreckage, the end of the beam would be dripping molten steel."

"Peter Tully, president of Tully Construction of Flushing, New York, told AFP that he saw pools of «literally molten steel» at the World Trade Center. Tully was contracted on September 11 to remove the debris from the site.

Tully called Mark Loizeaux, president of Controlled Demolition, Inc. (CDI) of Phoenix, Maryland, for consultation about removing the debris. [...].

Loizeaux, who cleaned up the bombed Federal Building in Oklahoma City, arrived on the WTC site two days later and wrote the clean-up plan for the entire operation.

AFP asked Loizeaux about the report of molten steel on the site. «Yes,» he said, «hot spots of molten steel in the basements.»

These incredibly hot areas were found «at the bottoms of the elevator shafts of the main towers, down seven [basement] levels,» Loizeaux said. The molten steel was found «three, four, and five weeks later, when the rubble was being removed,» Loizeaux said. He said molten steel was also found at 7 WTC, which collapsed mysteriously in the late afternoon."

"I didn't personally see molten steel at the World Trade Center site. It was reported to me by contractors we had been working with. Molten steel was encountered primarily during excavation of debris around the South Tower when large hydraulic excavators were digging trenches 2 to 4 meters deep into the compacted/burning debris pile. There are both video tape and still photos of the molten steel being «dipped» out by the buckets of excavators. I'm not sure where you can get a copy."

Public health advisor Ron Burger, a veteran of disasters from the Mississipi floods to Mt. St. Helens who arrives at Ground Zero on September 12, said: "Feeling the heat, seeing the molten steel, the layers upon layers of ash, like lava, it reminded me of Mt. St. Helens [...]."

"Summary for Sample 1

The thinning of the steel occurred by a high-temperture corrosion due to a combination of oxidation and sulfidation.

Heating of the steel into a hot corrosive environment approaching 1,000 °C (1,800 °F) results in the formation of a eutectic mixture of iron, oxygen, and sulfur that liquefied the steel.

The sulfidation attack of steel grain boundaries accelerated the corrosion and erosion of 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."(1)

"Perhaps the deepest mystery uncovered in the investigation involves extremely thin bits of steel collected from the trade towers and from 7 World Trade Center; a 47-story high rise that also collapsed for unknown reasons. The steel apparently melted away, but no fire in any of the buildings was believed to be hot enough to melt steel outright."

"Jonathan Barnett, professor of fire protection engineering, has repeatedly reminded the public that steel - which has a melting point of 2,800 degrees Fahrenheit - may weaken and bend, but does not melt during an ordinary office fire. Yet metallurgical studies on WTC steel brought back to WPI reveal that a novel phenomenon - called a eutectic reaction - occurred at the surface, causing intergranular melting capable of turning a solid steel girder into Swiss cheese. [...] The New York Times called these findings «perhaps the deepest mystery uncovered in the investigation.» [...]. This Swiss cheese appearance shocked all of the fire-wise professors, who expected to see distortion and bending - but not holes."
