Abstract

L'invention concerne un acier faiblement allié dans lequel est exécuté un traitement thermique après soudage, et qui est constitué, en % en masse, de C : 0,01 à 0,15%; Si : 3% au plus, Mn : 3% au plus et Al : 0,08% au plus. Un élément ou plus choisi parmi Ti, V et Nb, est compris dans une plage satisfaisant la formule (1). Le reste est constitué de Fe et d'impuretés inévitables. Les impuretés inévitables consistent en N : 0,01% au plus, P : 0,05% au plus, S : 0,03% au plus, et O : 0,03% au plus. Cet acier faiblement allié possède une excellente résistance à une fragilisation causée par un hydrogène, telle qu'une corrosion fissurante sous tension dans un environnement humide de sulfure d'hydrogène, dans une zone thermiquement affectée. 0,1×[C(%)]?[Ti(%)]+[V(%)]+0,5×[Nb(%)]?0,2 (1). Chaque symbole élémentaire contenu dans la formule renvoie à la teneur (% en masse) relative à chacun de ces éléments.
