Though it's quite an easy task to tell the difference between unrelated metals like Steel and Aluminum, it can be quite a little tougher to differentiate between iron materials that have been Hot Rolled from these that have been Cool Finished. The basic meaning of Hot Rolled Steel: Steel that's been approved by way of a pair of metal rollers while retaining the temperature of the substance well above its recrystallization temperature. This means that the metal is heated until it is warm enough to form (over 1700 degrees Fahrenheit) and then pushed by way of a set of rollers, taking whatever shape that the rollers allow the metal to consider. This technique isn't rapid, and the outer lining takes on a characteristic bluish-grey finish in the oxidation that occurs when the warm material cools in the wild atmosphere of the work.

With this moving method, the inventory is doused in gas, which keeps the material unoxidized, keeping the top clean and the natural gray color of the actual steel. Hot Rolled is produced at much higher temperatures and isn't washed in fat, allowing for more versatility in developing the steel, but in addition allowing for greater rust. § Most types of Hot-Rolled are more maleable than Cold-Rolled Steel.
