What is cold drawing?

Cold-drawing is to forcibly stretch the steel bar at room temperature with a tensile stress exceeding the original yield point strength of the steel bar, so that the steel bar is plastically deformed, thereby improving the yield point strength of the steel bar and saving steel.

Cold drawing-is a material processing technology. For metal materials, cold drawing refers to drawing at room temperature to achieve a certain shape and certain mechanical properties. Compared with thermoforming, cold-drawn products have the advantages of high dimensional accuracy and good surface finish.
