Melting Steel

Consider . .

1. The melting point of steel at 2,800 degrees F is about 1,000 degrees higher than the maximum burning temperature of jet-fuel-based fires, which do not exceed 1,800 degrees under optimal conditions.
2. The NIST examined 236 samples of steel and found that 233 had not been exposed to temperatures above 500 degrees F and the others not above 1200.
3. Underwriters Laboratory certified the steel in the buildings up to 2,000 degrees F for three or four hours without any significant effects, where these fires burned neither long enough or hot enough—at an average temperature of about 500 degrees for about one hour in the South Tower and one and a half in the North—to weaken, much less melt.
4. If the steel had melted or weakened, then the affected floors would have displayed completely different behavior, with some degree of asymmetrical sagging and tilting, which would have been gradual and slow, not the complete, abrupt and total demolition that was observed.
