Carbon steel plate is a steel plate with carbon as the main alloying element. Its mechanical properties mainly depend on the carbon content. It is usually divided into low carbon steel (such as Q235), medium carbon steel (such as 45#) and high carbon steel (such as T8). Low carbon steel plate has good plasticity and is easy to weld. It is widely used in buildings, bridges and mechanical structures; medium carbon steel plate has both strength and toughness, suitable for gears and shaft parts; high carbon steel plate has high hardness and strong wear resistance, and is often used for knives, springs, etc.

Carbon steel plate has the characteristics of low cost, good processability and wide application range. It is one of the most basic and largest steel materials in industrial manufacturing and engineering construction.

According to the production process, carbon steel plate can be divided into hot-rolled plate and cold-rolled plate. Hot-rolled plate has a rough surface but high strength, and is often used in heavy structures; cold-rolled plate has high dimensional accuracy and smooth surface, and is mostly used in precision manufacturing such as automobiles and home appliances.

In addition, carbon steel plate can also be improved through galvanizing, painting and other treatments to improve corrosion resistance to meet different environmental requirements. Whether it is construction, machinery, ships or daily hardware products, carbon steel plates play an irreplaceable role and are an important basic material for modern industry.
