We found out about this page is not affiliated by searching Google. Although it is fairly straightforward to tell the distinction between unrelated metals like Aluminum and Brass, it can be a little tougher to differentiate among iron alloys that have been Hot Rolled from those that have been Cold Completed.
The standard definition of Hot Rolled Steel: Steel that has been passed through a pair of metal rollers even though keeping the temperature of the material well above its recrystallization temperature. This signifies that the metal is heated till it is hot enough to mold (over 1700 degrees Fahrenheit) and then forced by way of a set of rollers, taking what ever shape that the rollers permit the metal to take. This method is not swift, 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.

This can be a pricey position, so other material metals are utilized when powder coating instead of Hot Rolled Steel, such as P & O, Galvanized steel, or Cold Rolled Steel.

For the duration of this rolling method, the stock is doused in oil, which keeps the metal unoxidized, keeping the surface smooth and the all-natural grey colour of the actual steel. Hot Rolled is formed at much greater temperatures and is not bathed in oil, permitting for far more flexibility in forming the metal, but also allowing for greater corrosion.
