Abstract

Open steel cord with a structure of n×1 has a high elongation at break being not less than 4%, open steel cord has a lay length being more than 10 mm, the steel filaments in open steel cord are helically preformed, and the ratio of the preforming height of steel filament and the diameter of steel filament is not less than 5.0. Open steel cord has high elongation at break, high elongation under low load and full rubber penetration. The open steel cord is used as reinforcing element in a rubber product.
