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.
