In GB Patent 2353804, Toyo Kohan Co. Ltd describes a resin-coated steel sheet suitable for use in a thin-walled, deep drawn, ironed can which is excellent for processing. It has resistance to surface roughing and corrosion. A raw steel sheet or a coated steel sheet for a resin-coated steel sheet is suitable for use in a thin-walled, deep drawn, ironed can. The coated steel sheet is characterised in that the raw sheet has a composition 0.008 to 0.08%, Si <0.05%, Nn < 0.9, P < 0.04%, S < 0.04%, A1 < 0.03%, N < 0.0035%,the remainder being Fe and obligatory impurities. It has an average diameter of crystal grains of 8m or less,, an average surface roughness (Ra) of 0.5m or less, and a maximum surface roughness (Rinax) or 0.5m or less.
