mechanical properties and welding characteristics of a commercial, dual-phase, low-carbon, cold-rolled steel are described. the new steel, hi-form 80d, exhibits a total elongation of about 24% as produced and develops a yield strength of about 625 mpa (91 ksi) in a formed and paint-baked part. property uniformity is excellent and the weldability essentially equivalent to an aisi 1006 steel. in addition, the aging response of hi-form 80d is such that ...
