What is HR Coil?
HR Coil or hot rolled coil are made by rolling the steel continuously at high temperatures, which is generally above 1000 degrees F. The process includes passing the metal sheets which are manufactured from billets through the rollers. The process is conducted above the recrystallization temperature of the given grade of stainless steel. Depending on the dimensions specified by the clients, the metal sheet might be passed through the rollers several times. The Hot Rolled Coil is manufactured as soon as possible without much delay so as to avoid the need for reheating the steel during the whole manufacturing process. As the steel cools off, it shrinks and thus it is not easy to determine the shape and size of the end product. This entire manufacturing procedure is known as hot rolling.
What are Hot Rolled Steel Sheet?
The Hot Rolled Steel Sheet is basically a steel which is roll pressed at a very high temperature (above 1700 degrees F). This temperature is selected as it is above the recrystallization temperature for most of the steel grades. Doing so, enhances the formability of the steel and hence the resultant products are easier to work with. The Hot Rolled Steel Plate and sheet is mostly used in welding and boiler making. They are ideal for making products such as railroad tracks and i-beams.
Difference between HRC & CRC?
The primary difference between HRC and CRC is the way in which both of them are processed. For manufacturing Jindal HR Coil, the steel is roll-pressed at a very high temperature which is usually above 1700 degrees C, as it is above the recrystallization temperature for most of the steel grades. Whereas, for manufacturing the cold rolled coil, firstly hot rolled steel is taken and then it is further processed in various cold reduction materials. The cold rolling procedure takes place at nearly room temperature.

Is hot rolled or cold rolled steel stronger?
In terms of physical characteristics, the cold rolled steel is usually harder and stronger when compared to the Hot Rolled Strips. This is because unlike the manufacturing procedure of Hot Rolled Plate, the cold rolled steel is shaped at lower temperatures. This enhances the hardness, tension breaking resistance, and deformation resistance of the steel. All these happen due to the process of work hardening.
