Reduced weight, adhesion optimized steel / plastic / composite steel sheet having excellent suitability for resistance welding
2016
Reduced weight, adhesion optimized steel / plastic / steel composite sheet A, B with excellent suitability for resistance welding, in particular spot welding, wherein the steel a thermoplastic plastics intermediate layer 3 is connected so that between two cover sheets 1, 2, characterized in that the cover plates weight following alloy composition in. - comprise%: C 0.04 to ≤ 1.0, Al 0.05 to <4.0, Si 0.05 to ≤ 6.0, Mn 9.0 to <18.0, the remainder being iron, including typical steel companion elements and optional alloying of Cr, Cu, Ti, Zr, V and Nb, and the cover plates 1, 2 at deformation a TRIP and / or TWIP effect and the plastic intermediate layer 3 facing sides of the cover plates 1, 2, from the cover plate 1, 2 mechanically worked and molded and suitable for mutual entanglement secondary shaped elements 4, 5 which have, said experie by the previous molding a strength increase compared to the unprocessed cover plate 1, 2 have en and are dimensioned in their number and height so that the side mold members 4, 5 of the cover plates 1, 2 is caught against each other or to the opposite cover plate 1, 2 and the cover sheets 1, are secured 2 against relative displacement and thereby an electrical contact form between the cover plates 1, 2, allow the resistance welding of the composite sheet a, B.
