Abstract

Alliage d'acier inoxydable, non magnétique, austénitique, résistant à la corrosion, à usinabilité améliorée, avec un coefficient d'expansion thermique régulièrement reproductible et une structure pratiquement exempte de ferrite. L'alliage renferme environ 0,04-0,10 % en poids de C, 0,03-0,07 de N, 2,00 au max. de Mn, 1,00 au max. de Si, 0,045 au max. de P, 0,015-0,10 de S, 19,00-24,00 de Cr, 0,75 au max. de Mo, 12,00-18,00 de Ni, le reste étant constitué de fer. L'alliage est équilibré de telle façon qu'il ne renferme pas plus de 2 % environ en vol. de ferrite, selon le diagramme de DeLong, et que le coefficient d'expansion thermique soit d'environ 14,5 x 10 -6 à 16,5 x 10 -6 par degré C dans une plage de température d'environ -51 à 121 degrés C, et ne renfermant pas plus de 2 % en vol. de ferrite selon le diagramme de DeLong, ce qui en fait un alliage non magnétique.
