ABSTRACT:
A method of making high-strength steel structural members is disclosed by providing a blank of high-strength steel having a ferrite-pearlite microstructure and high-strength mechanical properties and cold forming the blank by rolling, upsetting, forging, or extrusion to provide a structural member having a desired geometric cross-section while the mechanical strength of the structural member remains substantially the same or greater than the blank.
