The drawing material SCM435 was attempted in this study. The experiments were carried out under three different lubricating conditions: wiredrawing powder, oil and grease to analyze its optimum stretch working conditions. In the research process, the experiment and simulation analysis of the fixed shear friction ring were used to obtain the friction coefficient under three different lubricating conditions. Then the forming software DEFORM-3D was utilized to simulate the wire drawing process under different friction coefficients to obtain the load and stress distribution required for wire drawing. The research results show that the wire drawing powder has the smallest friction coefficient and the lowest surface hardness in the experiment of the drawing material. The effective stress was generated on the wire drawing die is also the smallest of the three different lubrication conditions. Moreover, during the forming simulation of wire drawing material SCM435 on wire drawing powder or wire drawing oil, the stress of the wire drawing die will not exceed the yield strength of SKD61.
