  • the invention relates to a method for producing seamless steel tubes or flat products (strip and sheet) for tubes or
  • Containers that are intended for the conveyance, transport or processing of hydrocarbons. In the presence of CO 2 and water and possibly small amounts of H 2 S, there are corrosive conditions in the media to be transported or processed.
  • Corrosion-resistant steels are used to meet the high requirements with regard to corrosion resistance, especially the
  • a suitable steel can be found, for example, in DE 26 15 599 C2. Because of the high proportions of expensive alloying elements (for example 22% Cr, 5% Ni, 3% Mo), pipes and containers made from such steels are extremely cost-intensive for the above-mentioned applications. These relatively high-strength duplex steels usually have low C contents and are therefore easy to weld. Steels containing 0.18 - 0.22% C and 12.5 - 1.% Cr are also known for use in oil fields (material RISI 420). This material has very good corrosion resistance in a humid CO 2 environment. Since pipes made of this material are practically not weldable under construction site conditions, only the pipes are connected
  • chromium steels are known for the production of steel pipes, which are weldable.
  • An example of this is the material RISI 410 (material no. 1.4006), which 0.06 - 0.12% C, max. Contains 1.0% Mn and 12.0 - 14.0% Cr.

  • the Cr solL content is in the range from 12.0 to 13.8%. Values in the range 0.02-0.04% have proven to be particularly favorable for the addition of Nb; however, a range of 0.01-0.05% is permissible. Since the C content is 0.015 - 0.035%

  • the second rolling phase is preferably carried out in such a way that, when accelerated from a final rolling temperature of greater than or equal to 850 ° C., the cooling rate is at least 5 K / s to below 200 ° C. Further cooling can take place in air. Subsequent starting is recommended, but is not absolutely necessary.

Abstract

L'invention concerne un procédé pour la fabrication de tubes d'acier ou de produits plats (feuillard ou tôle) sans soudure pour des tubes ou des récipients destinés à délivrer, transporter ou traiter des hydrocarbures gazeux liquides contenant du CO2 et de l'eau et éventuellement de faibles proportions de H2S et offrant une résistance à la corrosion fissurante par contrainte tout en présentant une bonne soudabilité et une limite d'élasticité 0,2 % d'au moins 450 N/mm2. On emploie un acier contenant du Ni et présentant également la composition suivante (% en poids): min. 0,015 % C, 0,15-0,50 % Si, max. 2,00 % Mn, max. 0,020 % P, max. 0,003 % S, 12,0-13,8 % Cr, 0,002-0,02 % N, 0,01-0,05 % Nb, reste: fer et impuretés courantes. Dans le cadre de l'invention, il est proposé que la teneur en Ni soit limitée à un maximum de 0,25 %, que la teneur en Mn soit d'au moins 1,0 %, que la teneur en C soit limitée à 0,035 % et que le produit comporte, en tant que constituant additionnel d'alliage, 0,01 à 1,2 % de Mo.
