Also, the surface has a scaly finish. This is a kind of oxide that forms at high temperatures, known as mill scale. It is easy to identify hot rolled products by touching the surface because of the uneven finish but it is also lacking an oily film. With steel bars, the corners are rounded. Hot Rolled Steel Uses
1D Stainless Steel Finish Hot Rolled, Annealed amp; Pickled. After the steel is hot rolled in the mill, it is then put through a heat treatment called annealing. Annealing consists of heating the steel and letting it cool down slowly to remove internal stress and reduce hardness. This makes it

Hot rolling is a process in a steel plant in which the semifinished slab is reheated to a predetermined temperature and the hot slab is rolled to make the specified hot strip in a coiled form. The role of a hot strip mill (HSM) is to produce strips from semifinished steel slabs.
Mill scale is found on all hotrolled steel products unless processed in a protective atmosphere or descaled (, for galvanizing). At hot rolling temperatures, an inner layer of w#252;stite, FeO, exists between the steel and magnetite.
#0183;#32;Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700#176; F), which is above the steels recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.
They are reheated in the soaking pits and are hot rolled next, in hot strip mills. The layers of scale are removed by pickling and further reductions are obtained by cold rolling. One of the traditional aims of hot rolling is to reduce the size of slab at as high a temperature as possible, thereby reducing the mill loads and increasing the tonnage.

The AR finish (meaning as rolled) is our standard for hot rolled sections in in carbon steel, which is defined by EN 10025. The hot rolling and the final straightening process affect the surface. Admissible imperfections are defined by the EN 101633. Hot rolled profiles from Montanstl have in their crude condition an aboveaverage good surface and are already with the standard mill finish suitable for a
Our Blackened Hot Rolled finish is simple. We use Hot Rolled Steel and clean the original mill scale of the steel to a blue black finish that has a clean, durable, classic industrial look. Actual colors in finish may vary slightly from sample image shown. All patinad surfaces will be sealed with an acrylic sealer, clear powder coat, or oil amp; wax

Mill finishes, whether hot or cold rolled, are the basic supply condition for all stainless steel flat products. They are used universally for standard building components but are also the basis for subsequent finishing processes that alter the surface to meet more demanding architectural requirements. Four particular surface designations are im
Hot rolled surface finishes The use of stainless steel is increasing fast due to the material''s durability and corrosionresistance. If the right grades and surface finishes are selected, stainlesssteel lasts hundreds of years making it the least expensive material, thanks to its lowmaintenance costs.
