Abstract

Alliage d'acier inoxydable austénitique non magnétique, à l'état corroyé, exempt de ferrite et présentant une perméabilité magnétique relative inférieure à environ 1,02, une limite conventionnelle d'élasticité à 0,2 % à température ambiante d'au moins environ 100ksi, ainsi qu'une bonne résistance à la fissure de corrosion sous contraintes dans des environnements de chlorure. Les plages de teneur grande, intermédiaire et préférée sont représentées dans le tableau (I), le solde étant du fer. L'alliage est équilibré pour être sensiblement exempt de ferrite et pour présenter une bonne résistance à la fissure de corrosion sous contraintes au chlorure avec les relations suivantes en % en poids: N Í Mn + Cr -21,9/20; Ni + 2(Cu) Í Cr + Mo-14,6/1,5; et Mn < Cr + Mo.
