Iron has a melting point of 1535.0 degrees Celsius or 2795.0 degrees Fahrenheit. It has a boiling point of 2750.0 degrees Celsius or 4982.0 degrees Fahrenheit. Continue Reading.
At room temperature, iron is in the form of ferrite, or Î±-iron, a body-centered cubic structure. The density of Î±-iron is 7.86 g/cc. At 910Â°C it changes to Î³-iron, which is face-centered cubic and somewhat softer. At 1535Â°C iron melts, and boils at 3000Â°C.
