Abstract: Disclosed is a process for the heat treatment of metal strip material providing mechanical properties that differ over the width of the strip, wherein the strip is heated and cooled and optionally over-aged during a continuous annealing process. At least one of the following parameters in the process differs over the width of the strip: heating rate, top temperature, top temperature holding time, cooling trajectory after top temperature; or, when over-aging is performed, at least one of the following parameters in the process differs over the width of the strip: heating rate, top temperature, top temperature holding time, cooling trajectory after top temperature, over-aging temperature, over-aging temperature holding time, lowest cooling temperature before over-aging, re-heating rate to over-aging temperature. Also, at least one of the cooling trajectories follows a non-linear temperature-time path. Also disclosed is strip material thus produced.
