1. Overview of Hot Rolled Steel Plate

Hot-rolled steel plate is a type of steel material produced through the hot rolling process. This process involves heating steel slabs and then rolling them through rollers at high temperatures to form the final steel plate. Hot rolling alters the internal structure of the steel, providing favorable mechanical and physical properties.

Hot-rolled steel plate is an essential material in industry, widely used across multiple sectors. The main characteristic of hot-rolled steel plate is that it is manufactured at high temperatures, resulting in steel sheets with both high strength and ductility. Thanks to these properties, hot-rolled steel plates have diverse applications and play a vital role in industrial production.

2. Features of Hot Rolled Steel Plate

Compared with sheets or coils, hot rolled steel plates are known for their outstanding flatness, mechanical properties, and superior performances when it comes to strength, fabricability, toughness, etc.
Hot rolled steel sheets can be further processed by heat treatment in order to improve their mechanical properties.
