    Abstract: A steel cord (10) adapted for the reinforcement of elastomers comprises: a core steel filament (12) with a core steel filament diameter dc and coated with a polymer (14); six intermediate steel filaments (16) with an intermediate steel filament diameter di smaller than or equal to the core steel filament diameter dc; these intermediate steel filaments (16) are twisted around the core steel filament (12); ten or eleven outer steel filaments (18) with an outer steel filament diameter do smaller than or equal to the intermediate steel filament diameter dl; these outer steel filaments (18) are twisted around the intermediate steel filaments (16), the outer steel filaments (18) are preformed in order to allow rubber penetration inside the core (10). The core steel filament (12), the intermediate steel filaments (16) and the outer steel filaments (18) all have a tensile strength at least 2600 MPa. The cord (10) has an outer diameter D according to following formula: D≦dc+2×di+2×do+0.1 wherein all diameters are expressed in millimeter (mm).

    Abstract: A process of patenting at least one steel wire (10) with a diameter less than 2.8 mm. The cooling is alternatingly done by film boiling in water (14, 16) during one or more water cooling periods and in air during one or more air cooling periods. A water cooling period immediately follows an air cooling period and vice versa. The number of the water cooling periods, the number of the air cooling periods, the length of each water cooling period are so chosen so as to avoid the formation of martensite or bainite.
