Abstract (en)
[origin: WO2012136270A1] The present invention is related to a rolled steel sheet suitable for enamelling, said sheet having a carbon profile, defined by a gradient in the C-level from a level Csurface at least one surface of the sheet, to a level Cbulk in the bulk of the sheet, Cbulk being higher than Csurface, and With I - Cbulk higher than 0 and lower than or equal to 0.08wt%, - CsurfaCe between 0 and 0.015wt%, - A1 between 0.012wt% and 0.07wt%, Mn between 0.12wt% and 0.45wt%, 0 lower than 0.01wt% and optionally : - Cu between 0.025wt% and 0.1wt%, - S between 0.008wt% and 0.04wt%, - Ca between 0.0005wt% and 0.005wt%, the balance being Fe and incidental impurities, and wherein the depth where the C-level reaches (Cbulk+Csurface) 12, is higher than 75µm. The invention is equally related to a method for producing said steel sheet.
