HR COIL

HR coil, also known as Hot Rolled Coil, is a flat-rolled steel product that undergoes hot rolling processes to form coils of specific thicknesses and widths. This manufacturing method involves passing steel slabs or billets through a series of rollers while they are hot, typically above the recrystallization temperature. The resulting coils exhibit improved mechanical properties, making them suitable for various industrial applications.

COMPOSITION

HR coils are primarily made of carbon steel, but they can also contain alloying elements such as manganese, silicon, and traces of other elements depending on the specific requirements of the application.

SURFACE & FINISH

HR coils may have a characteristic scale or oxide layer on their surface due to the hot rolling process. The surface finish can range from a rough, scaled surface to a smoother finish, depending on subsequent processing steps such as pickling, oiling, or coating.

THICKNESS & WIDTH

HR coils are available in a wide range of thicknesses and widths, catering to various industrial requirements. Common thicknesses typically range from 1.2mm to 25mm or more, while widths can vary from 600mm to 2000mm or beyond.

STRENGTH & DURABILITY

HR coils exhibit high tensile strength, excellent formability, and good weldability, making them suitable for applications requiring structural integrity, versatility, and ease of fabrication.



USES:

Automotive Industry

HR coils find extensive use in the automotive sector for manufacturing various components such as chassis frames, structural parts, wheel rims, and body panels. Their high strength, formability, and weldability contribute to the performance, safety, and durability of automobiles.
