Emulsion intended for a lubricating treatment of a steel sheet surface, where the additive is selected from the group of O, O-dialkyl-hydroxybenzyl dithiophosphates. Bare steel sheets treated with this emulsion have very good tribological properties, even if the emulsion density applied is less than or equal to 1 g / m2 in the dried state. Oiled sheets with a dry appearance can be obtained which do not require re-oiling before shaping , even by stamping. |
