Title (EN) STAINLESS STEEL FOR FILTER APPLICATIONS.
(FR) ACIER INOXYDABLE POUR FILTRES
Abstract: front page image
(EN)The present invention relates to a filter comprising a porous sintered stainless steel. The filter includes 10- 30% chromium, 5-25% nickel, 0.5-3% manganese, 1-4% silicon, 0-3% molybdenum the remainder being iron and inevitable impurities. The sintered steel has a density less than 80% of full density. The invention also relates to the use of a stainless steel powder for the preparation of a filter having improved permeability at high temperatures .
(FR)La présente invention concerne un filtre comprenant de l'acier inoxydable fritté poreux. Le filtre comprend de 10 à 30 % de chrome, de 5 à 25 % de nickel, de 0,5 à 3 % de manganèse, de 1 à 4 % de silicium, de 0 à 3 % de molybdène, le reste étant du fer et d'inévitables impuretés. L'acier fritté présente une densité inférieure à 80 % de la densité totale. L'invention concerne également l'utilisation d'une poudre d'acier inoxydable pour la préparation d'un filtre présentant une perméabilité améliorée à température élevée.
