maybe you need to actually read about the steel from the towers and wtc 7.
"Summary for Sample 1
1. The thinning of the steel occurred by a high-temperture corrosion due to a combination of oxidation and sulfidation.
2. 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.
3. The sulfidation attack of steel grain boundaries accelerated the corrosion and erosion of the steel.
"Suggestions for Future Research"
"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. The rate of corrosion is also unknown. It is possible that this is the result of long-term heating in the ground following the collapse of the buildings. It is also possible that the phenomenon started prior to collapse and accelerated the weakening of the steel structure. A detailed study into the mechanisms of this phenomenon is needed to determine what risk, if any, is presented to existing steel structures exposed to severe and long-burning fires. "
notice that they dont know when it started or the cause of the sulfur. how many of those items you listed contains sulfur? and do you really know how much sulfur one needs to form a eutectic at 1100C? i also noticed that the muratic acid boils about 100C. guess what temp was the "experts" think it occured at? well above 100C!!
