Hot rolled steel is carbon steel that is heated above the recrystallization point (typically 1,700°F or above), flattened to the desired size and thickness by high speed rolls, and processed into the necessary shape (e.g. Strip, Pipe, Bar, Plate, Sheet).
Hot-rolled carbon steel coils are widely used in welded pipes, steel structures, cable trays, shelves, hardware, machinery, electrical cabinets, vehicles and other industries.
Hot rolled carbon steel is carbon steel that has been roll-pressed at very high temperatures—over 1,700˚F, which is above the re-crystallization temperature for most steels. This makes the steel easier to form, resulting in products that are easier to work with.
To process hot rolled steel, manufacturers first start with a large, rectangular length of metal, called a billet. The billet is heated and then sent for pre-processing, where it is flattened into a large roll. From there, it is kept at a high temperature and run through a series of rollers to achieve its finished dimensions. The white-hot strands of steel are pushed through the rollers at high speeds. For sheet metal, rolled steel is spun into coils and left to cool. For other forms, such as bars or plates, materials are sectioned and packaged.

Hot-rolled carbon steel can often be identified by the following characteristics:
A scaled surface—a remnant of cooling from extreme temperatures;
Slightly rounded edges and corners for bar and plate products (due to shrinkage and less precise finishing);
Slight distortions, where cooling may result in slightly trapezoidal forms, as opposed to perfectly squared angles.
Hot-rolled carbon steel typically requires much less processing than cold-rolled carbon steel, which makes it a lot cheaper. Because hot rolled steel is allowed to cool at room temperature, it’s essentially normalized—meaning it’s free from internal stresses that can arise from quenching or work-hardening processes.
