Wire drawing of stress conditions as two compressive stress has tensile stress of Triaxial stress States, and three are the primary stress is compressive stress state compared to plastic deformation of drawing wire is easier to achieve. Drawing deformation to compressive deformation of tensile deformation for two of the three main State, the condition to play metal and plastic, and are more likely to surface defects and exposure. Drawing process of wire pass safety factor of deformation affected by restrictions pass deformation in smaller more drawing passes, so often used in the production of wire multi-pass consecutive high speed drawing.
