Abstract

Fil de forme en acier au carbone faiblement allié à hautes caractéristiques mécaniques et résistant à la fragilisation à l'hydrogène, destiné à être utilisé comme constituant de conduites flexibles pour le secteur de l'exploitation pétrolière off shore. Le fil présente la composition chimique suivante, exprimée en pourcentages pondéraux de la masse totale, 0,75 < C % < 0,95 et 0,30 < Mn % < 0,85 avec Cr ≤ 0,4%; V ≤ 0,16%; Si ≤ 1,40 % et de préférence ≥ 0,15%, et éventuellement pas plus de 0,06% d'Al, pas plus de 0,1% de Ni, et pas plus de 0,1% de Cu, le reste étant du fer et les inévitables impuretés venant de l'élaboration du métal à l'état liquide; le fil de forme a une structure perlitique avec des traces possibles de ferrite, sans bainite ni martensite ; le fil de forme a une résistance à la rupture d'au moins 1300 MPa.
