Abstract
A flexible hose or pipe () is reinforced by means of at least one flattened steel wire () with natural edges. The steel wire has a thickness-to-width ratio t/w below 0.95, a tensile strength Rexceeding 3500−2000×d, where d is the diameter of a circle having the same cross-sectional surface and where Ris expressed in Mpa and a permanent elongation at maximum load Aof at least 0.70%. The flattening of the steel wire () allows to recuperate ductility which has been lost as a result of the drawing until the final tensile strength R.
