Carbon steel wire mainly refers to metal wire drawn or processed from carbon steel. Carbon steel wire is widely used in various mechanical and engineering fields due to its high strength, high wear resistance and excellent elasticity. For example, high carbon steel wire is used to manufacture key components such as valve springs and sealing rings in exhaust valves due to its high strength and wear resistance; low carbon steel wire is widely used in construction, agriculture, handicraft production and other fields due to its good plasticity, toughness and weldability.
