A cylindrical rod of 1040 steel originally 11.4 mm (0.45 inch) in diameter is to be cold worked by drawing. Tensile strength of more than 825 Mpa (120,000 psi) and a ductility of at least 12% EL are desired. Furthermore, the final diameter must be 8.9 mm(0.35 inches). Explain how this may be accomplished. Could you achieve the same properties with a brass rod? explain
