The low carbon concentrations (0.05-0.15%) in mild steel do not have a major effect on the melting point of iron, which is 1538 centigrade. Looking at the Iron-Carbon phase diagram show that the reduction from this melting temperature will be only a few degrees. At higher concentrations of carbon (2-4%), as in cast iron, the melting temperature is substantially reduced. The alloy starts melting at 1154 centigrade, and is completely molten by 1200-1400 centigrade depending on carbon content.
heated up to kindling temperature of the mild steel
1550
pls refer to carbon-phase diagram... mild steel will be liquid and welded with temp. of >1300degC
Of course steel melts. That is how is shaped into steel objects.
where does the steel go befor it melts
Depends on the metal, but for steel it is hot enough to melt the steel- and steel melts at 2600-2800 degrees F.
steel is all three. when it is heated it melts into a liquid. if it is heated even more it evaporates into a gas. if gas steel is cooled it condenses into liquid steel and if liquid steel is colled even more it hardens into a solid again
mild steel is heavier
Each steel has another melting point; this temperature is approx. 1 200 0C.
1600 C
