The invention relates to a process for producing strip made of an iron-carbon-manganese alloy, in which:a thin strip, having a thickness of 1.5 to 10 mm, is cast directly on a casting machine from a liquid metal of composition, in percentages by weight: C ranging between 0.001 and 1.6%; Mn ranging between 6 and 30%; Ni<=10% with (Mn+Ni) ranging between 16 and 30%; Si<=2.5%; Al<=6%; Cr<=10%; (P+Sn+Sb+As)<=0.2%; (S+Se+Te)<=0.5%; (V+Ti+Nb+B+Zr+rare earths)<=3%; (Mo+W)<=0.5%; N<=0.3%; Cu<=5%, the balance being iron and impurities resulting from the smelting;the said strip is cold rolled with a reduction ratio ranging between 10 and 90% in one or more steps; andthe said strip undergoes recrystallization annealing.The invention also relates to a strip that can be produced by this process.
