The main features of hot-rolled steel plates include:

Processing properties: Hot-rolled steel plates have low hardness, are easy to process, and have good ductility. This makes it easier to shape and bend during processing.

Mechanical properties: Due to the softening of steel at high temperatures, hot rolling can improve the internal structure of the steel, making it tighter and stronger, thereby enhancing the mechanical properties. At the same time, under the action of high temperature and pressure, defects within the steel such as bubbles, cracks and looseness can be welded.

Surface quality: The surface quality of hot-rolled steel plates is relatively poor because an oxide layer is easily formed on the surface during the hot-rolling process and the smoothness is low.

Strength and toughness: Hot-rolled steel plates have relatively low strength, but good toughness and ductility. It is usually used to produce medium-thick plates and is suitable for applications requiring better plasticity.

Thickness: Hot-rolled steel sheets can be of greater thickness, in contrast, cold-rolled steel sheets are usually smaller.

Application fields: Hot-rolled steel plates are often used in the production of structural steel, weather-resistant steel, automobile structural steel, etc., and are suitable for the production of various mechanical parts and the manufacture of high-pressure gas pressure vessels.
