Definitions

  • the notching is intended to create an anchoring effect of the metal reinforcement in the concrete structure to prevent tearing and to develop a state of stress favorable to the mechanical strength of the structure.
  • it must satisfy geometric conditions defined in standards such as the international standard ISO / FDIS 6935-2, determined in such a way as to obtain sufficient anchorage.
  • the standards define minimum mechanical characteristics that must be satisfied by notched wires. These minimum mechanical properties include a minimum conventional yield strength, a minimum ratio of ultimate load to conventional yield strength, minimum elongation at break, and minimum total elongation of the load at maximum. tensile failure test of the wire. These minimum mechanical characteristics are intended to ensure that the reinforcements will be able to withstand adequately the forces to which they will be subjected when the structures in which they are integrated will be used. They are measured according to standard procedures also defined in [ISO / FDIS 6935-2].
  • the chemical composition of the duplex stainless steel comprises, in% by weight, 10 % ⁇ Cr ⁇ 31 % 0 , 4 % ⁇ Or + mn + Cu + Co ⁇ 12 % 0 , 02 % ⁇ NOT ⁇ 0 , 45 % Yes ⁇ 2 % MB ⁇ 6 % W ⁇ 2 % 0 , 005 % ⁇ VS ⁇ 0 , 1 % 0 , 01 % ⁇ Nb ⁇ 0 , 4 % 0 , 01 % ⁇ Ti ⁇ 0 , 4 % the rest being iron and impurities resulting from the elaboration.
  • the invention also relates to a method for manufacturing a notched wire according to the invention, according to which a cold notching of a wire rod is carried out by passing between notching rollers, with an overall reduction rate between wire rod initial and final notched wire less than 16%, the wire temperature during the notching being less than 400 ° C.
  • EX1 and EX2 are given as examples and the yarn “Comp” is given for comparison.
  • EX1 is in accordance with the first embodiment
  • EX2 is in accordance with the second embodiment.
