Durning my research paper on The Fall Of the World Trade Center

You need to do a search for metal fatigue to understand the World Trade Center failure. The temperature was not the only issue; manufacturing processes that created the steel was also an issue. Not to mention the loads, engineering, temperature, length of high heat exposure, and the fact that once the top parts collapsed, the load on the lower supports increased greatly because of the acceleration of gravity.
One thing to know... the metal did not necessarily melt. Steel is made from iron and carbon. At high enough temperatures, the heat causes the carbon inside of the steel to separate out, causing the remaining metal (i.e. iron) to lose strength and bend. Most of the metal in the trade center wasn't melted; it was fatigued. (There weren't piles of globular metal... there were piles of destroyed I-beams.)

It depends on the metal, some lead based metals will melt with as low as 500 degrees Fahrenheit, some rare metals can take over 3000 degrees to make them melt

dependsd on the metal at the low end , mercury is liquid art room temperature. some metals will melt in your hand or with a little friction ,bismuth is an example. iron/steel requires a temperature of several thousand degrees. uranium is even higher

different metals have different melting points. there are hundreds of metals, here is a handy chart to help you out with a few of the most common metals....
aluminum 1236°
copper 1982°
gold 1948°
iron/steel 2795°
lead 622°
mercury −37.89 °
nickel 2647°
platinum 3222°
silver 1764°
tin 450°
titanium 3020°
zinc 787°

every metal melts at a different temperature.
lead melts at only a few hundred degrees, you can melt it on a stove top
steel melts at several thousand degrees.
