| 摘要 |
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 at least one surface of the sheet, to a level Cbulk in the bulk of the sheet, Cbulk being higher than Csurface, and with: Cbulk higher than 0 and lower than or equal to 0.08 wt %, Csurface between 0 and 0.015 wt %, Al between 0.012 wt % and 0.07 wt %, Mn between 0.12 wt % and 0.45 wt %, O lower than 0.01 wt % and optionally: Cu between 0.025 wt % and 0.1 wt %, S between 0.008 wt % and 0.04 wt %, Ca between 0.0005 wt % and 0.005 wt %, the balance being Fe and incidental impurities, and wherein the depth where the C-level reaches Cbulk+Csurface)/2, is higher than 75 mum. The invention is equally related to a method for producing said steel sheet. |
