Description

hot rolled steel shrinks slightly during the cooling phase, resulting in a slight change in accuracy; thickness and width of the coil. The finished product does not always meet the specific goals originally intended. Therefore, for flat steel products, there are standard tolerances and ranges defined by the industry. The production of hot rolled steel is both an art and a science that really requires a delicate balance. Often, additional and off-the-shelf treatments are required for areas that require tight tolerances.
Hot-rolled mild steel has been rolled at high temperatures from slabs of cast steel over two inches thick to coils as thin as 1/16-inch thick.
Because the steel is hot rolled, the degree of reduction from the slab to the coil is high, so the surface of the coil is noticeably rough and slightly oxidized. Recommended for hot rolled strip of precise thickness and high formability.
