Steel and bolt producers have constantly been aiming to reduce the cost of cold formed components. Most of the available methods of achieving this cost reduction aim to avoid the final heat treatment stage and obtain the required mechanical characteristics by forming steel wire rods with structures in the as-rolled condition. Work has, therefore, been carried out to study the effect of different cold drawing reductions on medium and low carbon ferrite-pearlite structures, dual phase structures and bainitic structures. This research project has focused on the development of a low cost, low carbon, low alloyed steel that can be quenched directly during wire rod rolling. These low carbon, ductile, martensitic/bainitic structures should be able to be cold formed by conventional processes so as to obtain grade 8.8 bolts and fasteners without final heat treatment.
