The invention provides a method which allows reliable production of steel products from a light steel. The steel products according to the invention exhibit isotropic deformation behaviour and are ductile at low temperature with high yield strengths. This is achieved according to the invention by a method for producing a steel product, in particular a steel sheet or steel strip, wherein a steel strip or sheet is produced from steel which contains (in % by weight): C: <= 1.00 %, Mn: 7.00 to 30.00 %, Al: 1.00 to 10.00%, Si: > 2.50 to 8.00%, Al + Si: > 3.50 to 12.00%, B: < 0.01%, Ni: < 8.00%, Cu: < 3.00 %, N: < 0.60 %, Nb: < 0.30 %, Ti: < 0.30 %, V: < 0.30 %, P: < 0.01 % and iron and unavoidable impurities as the remainder, from which strip or sheet the finished steel product is subsequently produced by cold forming that takes place at a degree of cold forming of 2 to 25 %.

L'objectif de cette invention est de fournir un procédé de fabrication fiable de produits en acier à partir d'un acier léger, lesquels produits en acier présentent sous hautes limites d'élasticité un comportement isotrope à la déformation et sont ductiles à basse température. A cet effet, un produit en acier, en particulier une tôle ou bande d'acier, est fabriqué par un certain procédé à partir d'un acier contenant (en % en poids) : C : <= 1,00 %, Mn : 7,00 - 30,00 %, Al : 1,00 - 10,00 %, Si : > 2,50 - 8,00 %, Al + Si : > 3,50 - 12,00 %, B : < 0,01 %, Ni : < 8,00 %, Cu : < 3,00 %, N : < 0,60 %, Nb : < 0,30 %, Ti : < 0,30 %, V : < 0,30 %, P : < 0,01 %, le reste étant constitué de fer et d'impuretés inévitables, tôle ou bande d'acier à partir de laquelle le produit en acier fini est ensuite fabriqué par une déformation à froid à un degré de déformation à froid compris entre 2 et 25 %.
