Most steel has other metals added to tune its properties, like strength, corrosion resistance, or ease of fabrication. Steel is just the element iron that has been processed to control the amount of carbon. Iron, out of the ground, melts at around 1510 degrees C (2750°F). Steel often melts at around 1370 degrees C (2500°F). In a "controlled burn" (where oxygen and fuel are regulated in an optimal mix), jet fuel will reach a maximum temperature of 1800F(982C), which is still not anywhere near the temperature required to weaken the steel girders of a building to the point that the entire building plummeted to the ground. Yet molten steel was reported below the towers, suggesting that a very powerful "fuel" was used, set to burn or explode BELOW the building, not at its top. Thermite, an HTA (high-temperature accelerant) typically used in military operations, would have been able to liquefy the steel. Thermite can reach a temperature of 4500F (2482C) in 2 seconds, and steel begins to melt at 2750F (1510C). Jet A is the same stuff burned in conventional steel wall heaters. In an open-air office fire such as that at WTC (called a "dirty burn" kerosene or any hydrocarbon will burn at around 500-700F (260C to 371C). The FEMA report on 911 said that the jet fuel burned off after a few minutes and the fires from the office furniture and carpets were about 560F (293C) The special structural steel of the WTC has over 98% of its strength at those temperatures, and the WTC was built to hold 5 times its load. Highest wood burn at 575 oF to 1100 oF (300 - 600 oC ) the main energy in the wood is released when fuel vapors containing 40% to 60% of the energy burn.
