Confidence votes 25. Steel often melts at around 1370 degrees C (2500 Â°F). This varies depending on the specific steel alloy. The specific heat of steel varied from 420J/KG/Deg C at room temperature to 720J/KG/Deg C at 1535 deg C. This equates to a theoretical heat requirement of approximately 375KWh/mt to melt steel from room temperature. In practice, foundries use between 500 and 800 KWh /mt to raise steel to a little above its melting point of 1535deg C.
When some start to deform, this will throw extra load on the others, and a chain reaction of failure is certainly possible. And steel will certainly lose strength at high temperatures-typically about 50% at 1000 F, and 75% at 1100 F.
