The simple definition of Hot Rolled SteelSteel that has been passed by way of a pair of metal rollers whilst keeping the temperature of the material properly above its recrystallization temperature. This means that the metal is heated until it is hot adequate to mold (more than 1700 degrees Fahrenheit) and then forced via a set of rollers, taking whatever shape that the rollers let the metal to take. This procedure is not quick, and the surface takes on a characteristic bluish-grey finish from the oxidation that happens when the hot steel cools in the open air of the mill.
