4. Two steels are being considered for manufacture of as-forged connecting rods. One is AISI 4340 Cr-Mo-Ni steel capable of being heat-treated to a tensile strength of 260 kpsi. The other is a plain carbon steel AISI 1040 with an attainable Sut of 113 kpsi. If each rod is to have a size giving an equivalent diameter de of 0.75 in., is there any advantage to using the alloy steel for this fatigue application?

A cylindrical rod of 1040 steel having originally 11.4 mm in diameter is cold-worked by drawing (i.e. pulling through a die with a hole smaller than the original rod cross section). The circular cross section will be maintained during deformation. The deformed steel is desired to have tensile strength in excess of 825 MPa and ductility of at least 12% EL. The final diameter must be 8.9 mm. Explain how this may be accomplished.
