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.FAQ1.GX is Factory or Trade enterprise?
