Abstract

La définition d'intervalles précis de température et de temps pour le traitement de fil machine en acier inoxydable, ainsi que des exigences techniques et métallurgiques pour le traitement ultérieure du fil machine, a permis de trouver un procédé de traitement qui, bien qu'ayant des limites de température relativement larges, permet de traiter de manière univoque et dans une installation unique des fils machine en acier inoxydable aussi bien austénitique que ferritique, en obtenant en outre les caractéristiques particulières envisagées pour l'emploi ultérieur de fil machine, ainsi qu'une sensible économie d'énergie.
