Abstract

L'invention concerne un traitement thermique. Le procédé est caractérisé en ce que ledit tube se trouvant à une température à laquelle correspond au plus 15 % de ferrite, est soumis à une trempe martensitique et/ou bainitique, en ce que l'on règle les conditions du refroidissement intense jusqu'à une température inférieure à celle de formation de martensite, de façon d'une part à limiter les effets de la trempe à une couche superficielle du profilé et d'autre part, de telle façon qu'à la sortie de la phase de trempe, la partie du profilé la plus éloignée de la zone trempée se trouve à une température supérieure à 675 degrés C, et en ce qu'après cette phase de revenu, le tube est soumis à un refroidissement à l'air calme. Application aux tubes de toutes sortes obtenus par laminage, extrusion, filage ou autre moyen.
