A flexible hose or pipe (42) is reinforced by means of at least one flattened steel wire (10, 20) with natural edges. The steel wire has a thickness-to-width ratio t/w below 0.95, a tensile strength Rm exceeding 3500 - 2000 x d, where d is the diameter of a circle having the same cross-sectional surface and where Rm is expressed in MPa and a permanent elongation at maximum load Ag of at least 0.70 %. The flattening of the steel wire (10, 20) allows to recuperate ductility which has been lost as a result of the drawing until the final tensile strength Rm. <IMAGE> |
