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.
