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.
The melting point of most solder is in the region of 188Â°C (370Â°F) and the iron tip temperature is typically 330Â°C to 350Â°C (626Â°F to 662Â°F).Soldering Basics : Although tip temperature is not the key element in soldering you should always start at the lowest temperature possible.here is no proper soldering iron temperature just for a given type of solder-the iron temperature should be set for both the component and the solder. When soldering surface mount components, a small tip and 600F (315C) should be sufficient to quickly solder the joint well without overheating the component.
