Whilst it is pretty straightforward to tell the difference among unrelated metals like Aluminum and Brass, it can be a small harder to differentiate among iron alloys that have been Hot Rolled from those that have been Cold Finished. The basic definition of Hot Rolled Steel: Steel that has been passed via a pair of metal rollers while keeping the temperature of the material effectively above its recrystallization temperature. This indicates that the metal is heated till it is hot sufficient to mold (over 1700 degrees Fahrenheit) and then forced by means of a set of rollers, taking what ever shape that the rollers allow the metal to take. This process is not quick, and the surface requires on a characteristic bluish-grey finish from the oxidation that occurs when the hot steel cools in the open air of the mill.
