Definitions

  • Tungsten is generally used relatively rarely as an alloying element. As a strong carbide former, it is regularly used to manufacture cold, hot and high-speed steels. It increases their heat resistance, temper resistance and especially wear resistance at high temperatures. In its mode of action, tungsten is similar to molybdenum, so that it can replace molybdenum in a ratio of 2: 1.
  • the strength level can be lowered by higher tempering temperatures and increased by lower temperatures.
  • alloys can be selected which have the quality level range from X 52 to X 90 through appropriate remuneration treatment can represent.
  • the examined steel sample according to the invention showed a notched impact value of 92 J / cm 2 with regard to the notched impact strength at a test temperature of -30 ° C (sample position: sheet center, transverse), which is to be regarded as extraordinarily good for the quality class X 85.
  • the weldability of the steel according to the invention can be classified as completely satisfactory, and there is no discernible negative influence of the alloyed tungsten.

Abstract

La présente invention concerne un procédé de fabrication de tuyaux de conduite sans joint dans une gamme des niveaux de qualité X 52 à X 90, avec une limite d'élasticité stable jusqu'à une température d'utilisation de 2000 C et avec une caractéristique constante de tension-dilatation, consistant à soumettre à un processus de laminage à chaud un produit de départ pour tuyaux, à base d'un acier comprenant les composants d'alliage suivants ( % en poids): C (0,06 - 0,18 %), Si (max. 0,40 %), Mn (0,80 - 1,40 %), P (max. 0,025 %), S (max. 0,010 %), Al (0,010 - 0,060 %), Mo (max. 0,50 %), V (max. 0,10 %), Nb (max. 0,10 %), N (max. 0,015 %), W > 0,30 - 1 %), le reste étant constitué de fer et des impuretés habituelles. Après le laminage à chaud, les tuyaux refroidis sont réchauffés par l'intermédiaire d'AC¿3?, puis trempés à une vitesse de refroidissement d'au moins 15 °C/s et recuits dans une plage de températures entre 500 et 700 °C.
