Thor lighting is around 18,000°F. Did a little bit a research and some one said to melt steel around the size of a nut or a bolt you would have to use a plasma torch that could heat it to around 2500°F.. Even then would take about about 2 to 3 minutes to completely liquefy steel that size. MOS Superman did it in under a second to an entire I beam. They only way to instantly vaporize steel like that is with the heat from the core of a Nuclear bomb blast. That runs around 50 to 150 million degrees Fahrenheit. I may be wrong though.
