The traditional method for manufacturing high-strength fasteners involves the use of low-alloy steels in annealed or drawn and annealed conditions with the formed fasteners being hardened and tempered to develop the required properties. The objective of this project is to evaluate the potential for producing high-strength fasteners directly from as-rolled rod, without the need for a subsequent hardening heat treatment. It is concluded that as-rolled CSiMn and CMnNb steels are suitable for the production of high-strength fasteners. The desired properties can be developed in the as-formed component with subsequent tempering. This route offers cost reductions in terms of alloy content, elimination of drawing and annealing of rod and elimination of the conventional heat treatment processes on the finished fasteners.
