Hot Rolled Steel Acquiring metals can be a mystifying endeavor. For the most part, customers know which type (Bar, Plate, Strip, Tube, Sheet, etc.) they need to have, but not usually which kind of metal. While it is pretty easy to tell the difference among unrelated metals like Aluminum and Brass, it can be a little harder to differentiate among iron alloys that have been Hot Rolled from these that have been Cold Completed. The standard definition of Hot Rolled Steel: Steel that has been passed via a pair of metal rollers while keeping the temperature of the material properly above its recrystallization temperature. This signifies that the metal is heated until it is hot sufficient to mold (over 1700 degrees Fahrenheit) and then forced via a set of rollers, taking what ever shape that the rollers enable the metal to take.

Hot Rolled Steel – a couple of considerations  The characteristic bluish-grey tint of Hot Rolled Steel is brought on by mill scale. This Mill scale does not colour consistently—the bluish grey can fluctuate across a single piece—so it is ideal to not rely on an even coating of mill scale to supply the colour for your kind.  If you program on coloring Hot Rolled steel by powder coating, you have to initial expose the base metal by grinding away its shell of oxidation. This can be a expensive position, so other material metals are used when powder coating instead of Hot Rolled Steel, such as P &amp; O, Galvanized steel, or Cold Rolled Steel. How does Hot Rolled Steel differ from Cold Rolled Steel?  Cold-Completed, also referred to as Cold Rolled Steel, is stock that has been rolled at room temperature. Throughout this rolling process, the stock is doused in oil, which keeps the metal unoxidized, maintaining the surface smooth and the natural grey color of the actual steel. Hot Rolled is formed at much greater temperatures and is not bathed in oil, allowing for much more flexibility in forming the metal, but also enabling for higher corrosion.  Most types of Hot Rolled are far more maleable than Cold Rolled Steel. While this isn’t normally noticeable in most forms, you can see a difference in some of the smaller sizes.  At the corners and edges, Hot Rolled could seem to be a small rounded, with dimensions that may be much less exact than Cold Rolled Steel.
