  • Patent number: 6358338
    Abstract: 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; and the said strip undergoes recrystallization annealing. The invention also relates to a strip that can be produced by this process.

  • Patent number: 6328826
    Abstract: The invention provides a method of fabricating “TRIP” steel in the form of thin strip, wherein: a strip from 1.5 to 10 mm thick, preferably from 1 to 5 mm thick, is cast directly from liquid steel having the composition (in weight percent) C % from 0.05 to 0.25, (Mn+Cu+Ni) % from 0.5 to 3, (Si+Al) % from 0.1 to 4, (P+Sn+As+Sb) % not greater than 0.1, (Ti+Nb+V+Zr+rare earths) % less than 0.3, Cr % less than 1, Mo % less than 1, V % less than 1, the remainder being iron and manufacturing impurities; said strip is hot rolled on-line in one or more passes at a temperature higher than the Ar3 temperature of said steel and with a reduction ratio from 25 to 70%; first forced cooling of said strip is carried out at a cooling rate from 5 to 100° C./s; the strip remains at temperatures from 550 to 400° C.
