  • Patent number: 9617625
    Abstract: A process for the manufacture of a profiled wire of hydrogen-embrittlement-resistant, low-alloy carbon steel for flexible pipelines for the offshore oil and gas operations sector is provided. The process includes providing a low-alloy carbon steel wire rod having a composition including, expressed in percentages by weight of the total mass 0.75<C %<0.95; 0.30<Mn %<0.85; Cr?0.4%; V?0.16%; and Si?1.40%, the rest being iron and the inevitable impurities from smelting of the metal in the liquid state. The process further includes hot-rolling the wire rod in an austenitic region above 900° C.

  • Patent number: 9249486
    Abstract: A profiled wire, of NACE grade, made of low-alloy carbon steel intended to be used in the offshore oil exploitation sector is provided. The profiled wire includes the following chemical composition, expressed in percentages by weight of the total mass: 0.75<% C<0.95; 0.30<% Mn<0.85; Cr?0.4%; V?0.16%; Si?1.40% and preferably ?0.15%; and optionally no more than 0.06% Al, no more than 0.1% Ni and no more than 0.1% Cu, the balance being iron and the inevitable impurities arising from smelting the metal in the liquid state.
