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.
The temperature required to forge weld is typically 50 to 90 percent of the melting temperature. Iron can be welded when it surpasses the critical temperature (the A4 temperature) where its allotrope changes from gamma iron (face-centered cubic) to delta iron (body-centered cubic).
