The standard definition of Hot Rolled Steel: Steel that has been passed by way of a pair of metal rollers even though keeping the temperature of the material effectively above its recrystallization temperature. This dynamite success URL has a few staggering suggestions for where to consider this activity. This means that the metal is heated until it is hot enough to mold (more than 1700 degrees Fahrenheit) and then forced via a set of rollers, taking what ever shape that the rollers permit the metal to take.
