    Abstract: A high elongation steel cord (200), namely a cord having an elongation at break of greater or equal to 5%, comprises a plurality of strands (205) twisted together with a cord twist pitch. Said cord twist pitch results in a cord twist angle. Each strand (205) comprises a plurality of filaments (210) twisted together with a strand twist pitch resulting in a strand twist angle. The structural elongation of the high elongation steel cord (200) is greater or equal to 2.0% for a sum of the strand twist angle and the cord twist angle between 20 and 29 degrees, or said structural elongation is greater or equal to 2.5% for said sum between 30 and 38 degrees, or said structural elongation is greater or equal to 3.0% for said sum between 39 and 48 degrees. The steel cord is stable and durable and features high rubber penetration, and consequently is corrosion resistant.

    Abstract: This invention relates to a steel cord adapted for the reinforcement of rubber product. The steel cord (30) comprising a core strand (32) and three or more outer strands (34) twisted around said core strand (32). The outer strands (34) are multi- layer strands comprising multiple steel filaments arranged in an outer strand core (36) and at least one outer strand layer (38, 40), the steel filaments in the outer strands have a round or substantially round cross-section. At least one outer strand (34) comprises flattened portions (52) and non-flattened portions (54) along its length. The flattened portions create spacing S between adjacent outer strands (34) and gaps G between adjacent filaments in the outer strand (34), which improves rubber penetration and elongation of the steel cord (30), and finally improves the impact resistance of the steel cord (30). Besides, the flattened portions (52) limit the flare of the steel cord.

    Abstract: A steel cord (10) adapted for the reinforcement of elastomers, comprises a first group and a second group, the second group being helically twisted around the first group with a cord twisting step, the first group comprising a first number of first steel filaments (12), the first number ranging between three and eight, the second group comprising a second number of second steel filaments (14), the second number being equal to or greater than the first number, the first filaments having a twisting step greater than 300mm, both the first steel filaments (12) and the second steel filaments (14) being preformed. The steel cord has a PLE at a tensile tension of 50 Newton between 0.08% and 0.25%. This steel cord has measurable deformation to achieve full elastomer penetration, but also maintains the process-ability and functionality for elastomer reinforcement.
