Hot-rolled steel coils/plates are steels made by high-temperature heating and rolling. Its strength is not very high, but its plasticity and weldability are good. Hot rolling can improve the processing performance of metals and alloys, break the coarse grains in the as-cast state, heal cracks, reduce or eliminate casting defects, transform the as-cast structure into a deformed structure, and improve the processing performance of the alloy.

It's important to note that the main difference between hot rolled and cold rolled steel is one of process. "Hot rolling" refers to processing done with heat. "Cold rolling" refers to processes done at or near room temperature. Although these techniques affect overall performance and application, they should not be confused with formal specifications and grades of steel, which relate to metallurgical composition and performance ratings. Steels of different grades and specifications can be either hot rolled or cold rolled-including both basic carbon steels and other alloy steels.
It may seem obvious, but some types of steel are better suited for certain applications. Knowing which to use can help avoid over-spending on raw materials. It can also save time and money on additional processing. Understanding the differences between hot and cold steel is integral to choosing one over the other.
