What is a hot rolled coil?


A hot rolled coil (HRC) is a type of steel coil product that is produced through the hot rolling process. In this process, steel is heated above its recrystallization temperature and passed through a series of rollers to reduce its thickness.

The resulting product is a coil of steel that has a rougher surface finish and wider tolerances compared to cold rolled coils. This is because hot rolling causes some surface scaling and distortion, which can be removed through subsequent processes such as pickling or cold rolling.

HRCs are often used in a range of industrial applications, including construction, automotive manufacturing, and general fabrication. They are particularly well-suited to applications that require high strength and toughness, as well as those that involve bending or pressure forming.

The properties of HRCs can vary depending on factors such as the steel grade, thickness, and surface finish. However, in general, they are known for their high tensile strength, durability, and resistance to deformation under load.
