Also know, what is molten metal called?

What is the meaning of molten metal?
You're probably familiar with lava, the molten rock that explodes out of a volcano. Molten originated from the Old English verb meltian, meaning "become liquid." It takes incredibly high temperatures to get an object that was once rock solid to be transformed into a liquid state.
What temperature does steel soften?
It is known that structural steel begins to soften around 425°C and loses about half of its strength at 650°C. This is why steel is stress relieved in this temperature range. But even a 50% loss of strength is still insufficient, by itself, to explain the WTC collapse.
