Products Description
Hot Rolled Steel Coil/Plate
Hot rolled steel is an alloy consisting of iron and carbon. The percentage of carbon in the steel affects the hardness,strength of elasticity and ductility of carbon steel. As the carbon percentage content rises, steel is harder and strongerbut less ductile. Hot rolled steel has high hardness, toughness and strength, and it is relatively inexpensive compared toother steels.

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.
In addition, hot rolled steel shrinks slightly during the cooling phase, resulting in a slight change in accuracy; thickness and width of the coil. The finished product does not always meet the specific goals originally intended. Therefore, for flat steel products, there are standard tolerances and ranges defined by the industry. The production of hot rolled steel is both an art and a science that really requires a delicate balance. Often, additional and off-the-shelf treatments are required for areas that require tight tolerances. Hot-rolled mild steel has been rolled at high temperatures from slabs of cast steel over two inches thick to coils as thin as 1/16-inch thick.
Because the steel is hot rolled, the degree of reduction from the slab to the coil is high, so the surface of the coil is noticeably rough and slightly oxidized. Recommended for hot rolled strip of precise thickness and high formability.
Hot-rolled mild steel is less expensive than cold-rolled steel because it is not treated after hot rolling except that it requires pickling to remove surface scale. Hot Rolled Steel Coil Factory provides hot rolled mild steel plate and coil for your application.
