Hot Rolled Steel Coil Process

The first step in the hot rolling process is to heat the steel, elemental or mineral mixture to a high temperature above its recrystallization temperature. Once it is heated above this point, the steel becomes ductile. It is then sent to a rolling machine where it can be easily shaped. With this hot-rolled carbon steel process, it can produce large quantities of steel in a single batch as minimal additional machining is required.
After carbon steel is processed, it is normalized by cooling to room temperature. The process of heating and slow cooling of steel changes the metal's microstructure, increasing its ductility and strength. When forming steel, increasing ductility is an important factor in obtaining the desired shape. The exact combination of elements added to the iron content determines the grade of steel and its unique strength, formability and hardness properties. Carbon and manganese are the two main additional elements that affect the outcome of a particular grade of material, but other elements can also play a key role.
