Hot rolled steel is the most basic form of carbon steel.
Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel’s re-crystallization temperature. When steel is above the re-crystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes. When the steel cools off it will shrink slightly thus giving less control on the size and shape of the finished product. Hot rolled steel is used in situations where precise shapes and tolerances are not required.
Hot-Rolled Steel Sheets meeting a variety of standards ranging from mild steels to high-tensile strength steels. Variable sizes of coils and various surface finishes can be selected in accordance with customer needs.
Used in critical Engineering applications ( Automobile, General Engineering, Infrastructure, Machine Building, Fabrication, Material Handling, Railway Cars, Ships, Engineering and Military equipment, Storage tanks, Storage bins, bearing plates for buildings and other structural applications).
