How hot rolled steel is made?

The Heating Process

The process in which hot rolled is produced begins with heating slabs of steel to approximately 2,300 degrees Fahrenheit. The amount of heat directly affects the properties of the steel. Meaning, if the temperature is not high enough it can cause defects in the material.
