The steel is preheated, then heated and then plastic working is carried out immediately following heating, before the steel is finally cooled. A process for the plastic treatment of high strength two-phase sheet steel without altering sheet properties comprises preheating the sheet steel, heating to a temperature less than 400 degreesC, plastic working of the steel immediately following heating and finally cooling. An Independent claim is also included for the process apparatus, comprising a pre-heating device (2), a heating device (4), a plastic working device (5) and a cooling device (6). |
