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.
Sterling Silver melts at 1650 F, about 100 degrees less that pure silver because it is an alloy of 92.5% silver. You are not likely to use pure silver because it is too soft. Generally you melt your metal in a crucible, usually in an oven(not yout home oven, one made for casting), although a mega torch can do it.terling Silver melts at 1650 F, about 100 degrees less that pure silver because it is an alloy of 92.5% silver.
