Cold drawn round steel is a high quality metal material made by cold drawing process. It is made of hot-rolled round steel as billet, which is drawn by strong force at room temperature through a specific mold, so that the diameter of the round steel is accurately reduced. This process gives it many advantages: high dimensional accuracy and precise control of diameter deviation to meet the needs of precision manufacturing; The surface is very smooth, low roughness, reduce the subsequent grinding process; Due to the cold hardening effect, the strength and hardness are significantly improved, and the internal organization is uniform, and the mechanical properties are stable. Cold-drawn round steel is used in the field of machinery manufacturing to manufacture shaft, gear and other key parts; In the automobile industry, it is the ideal material selection for engine crankshaft, transmission shaft and other components; In the construction industry, it is often used to make strong connectors and support structures, and is widely used in many industries with strict material performance requirements.
