PCT No. PCT/FR91/00328 Sec. 371 Date Dec. 19, 1991 Sec. 102(e) Date Dec. 19, 1991 PCT Filed Apr. 19, 1991 PCT Pub. No. WO91/16461 PCT Pub. Date Oct. 31, 1991.A method of producing steel wires intended for the manufacture of flexible conduits, steel wires obtained by this method, and flexible conduits reinforced by such wires is characterized by the fact that, for a given strain-hardening rate of the initial wire, a heat treatment is carried out under conditions of time and temperature such that the steel wire obtained after treatment has a mechanical rupture strength (Rm) greater than 850 MPa and a structure containing little free ferrite. |
