| description | Die Erfindung betrifft einen hochfesten Mehrphasenstahl mit Mindestzugfestigkeiten von 750 MPa vorzugsweise mit Dualphasengefüge für ein kalt- oder warmgewalztes Stahlband mit verbesserten Umformeigenschaften und einem Streckgrenzenverhältnis von maximal 73%, insbesondere für den Fahrzeugleichtbau, bestehend aus den im Anspruch 1 angegebenen Elementen (Gehalte in Masse-%), Rest Eisen, einschließlich üblicher stahlbegleitender oben nicht erwähnter Elemente, die erschmelzungsbedingte Verunreinigungen darstellen.
The invention relates to a high-strength multi-phase steel having minimum tensile strengths of 750 MPa and preferably having a dual-phase microstructure for a cold- or hot-rolled steel strip, in particular for lightweight vehicle construction, said high-strength multi-phase steel having improved forming properties and a ratio of yield point to tensile strength of at most 73%. The high-strength multi-phase steel consists of the elements specified in claim 1 (contents in mass %), the remainder iron, including typical elements accompanying steel that are not mentioned above, which represent contamination resulting from smelting.
L'invention concerne un acier Multiphase à haute résistance présentant une élasticité minimale de 750 MPa, de préférence une structure double phase pour une bande d'acier laminée à froid ou à chaud, de meilleure propriétés de formage et un rapport d'élasticité de 73% maximum, notamment pour la construction légère d'automobiles, comprenant les éléments spécifiés dans la revendication 1 (teneurs en % en masse), le reste étant du fer, incluant des éléments habituels d'accompagnement de l'acier qui ne sont pas mentionnés ci-dessus, des impuretés dues à la fusion. |
