Application

1.Carbon steel plays an important role in the field of construction engineering. It can be used to make components such as beams, columns, bridges, and supports in building structures. Due to its good plasticity and weldability, carbon round steel is widely used in construction projects.
2.Carbon steel is also widely used in the mechanical manufacturing and manufacturing industry. In mechanical manufacturing, carbon round steel is often used to make components such as bearings, gears, racks, and connectors.
3.Carbon steel also plays an important role in the automotive manufacturing and transportation industries. A large amount of round carbon steel is required in automobile manufacturing to make components such as the body, chassis, and engine. The high strength and wear resistance of carbon steel make it the preferred structural material for automobiles.
4.Carbon steel is also widely used in shipbuilding and marine engineering. In shipbuilding, carbon round steel is mainly used to make ship structures, decks, and ship equipment. Due to its high corrosion resistance and seawater resistance, carbon steel is very suitable for use in marine environments.
