Abstract

La présente invention concerne un acier à
soudabilité améliorée présentant une bonne résistance à
la fissuration pour de fortes énergies de soudage, une bonne résilience à froid et ne nécessitant pas de préchauffage avant soudage. La composition pondérale de l'acier est la suivante:
- de 0,07 à 0,11% de carbone, - de 1,40 à 1,70% de manganèse, - de 0,20 à 0,55% de nickel, - de 0 à 0,30% de cuivre, - de 0 à 0,02% de niobium, - de 0,005 à 0,020% de titane, - de 0,002 à 0,006% d'azote, - de 0 à 0,15% de silicium, le reste étant du fer.
