Really? It took me ten seconds to find this on Wikipedia showing me it was clearly well above 500f...
The NIST found that the fireproofing on the Twin Towers' steel infrastructures was blown off by the initial impact of the planes and that, had this not occurred, the towers would likely have remained standing. A study published by researchers of Purdue University confirmed that, if the thermal insulation on the core columns were scoured off and column temperatures were elevated to approximately 700 °C (1,292 °F), the fire would have been sufficient to initiate collapse.
