Abstract (en)
[origin: WO2006042931A1] The invention relates to a method for production of a cold-laminated sheet of stainless austenitic iron/carbon/manganese steel, comprising the following steps: a sheet is provided, the chemical composition of which is, by weight, 0.35 % < C < 1.05 %, 16 %< Mn < 24 %, the remainder being iron and unavoidable production impurities, said sheet is cold-laminated, a recrystallisation annealing is carried out on said sheet in a furnace, containing a gas selected from the gases which are reducing with relation to iron, the annealing parameters being selected such that said sheet is covered on both faces with a sub-layer of essentially amorphous oxide (FeMn)O and an outer layer of crystalline manganese oxide MnO, the total thickness of the two layers being greater than or equal to 0.5 micrometers.
