Title (EN) FE-CR-AL ALLOY
(FR) ALLIAGE FE-CR-AL
(DE) FE-CR-AL LEGIERUNG
Abstract:
(EN) The invention relates to a ferritic, oxidation-resistant iron-chrome-aluminium-yttrium-hafnium alloy for thin films and wires. Said alloy has an improved life-span and a reduced oxidation speed at high temperatures, a high hot-drawing resistance and a high specific electric resistance. The alloy has the following composition (in percent by mass): Cr: 16-22, A1: 6-10, Si: 0.02-1.0, Mn: max. 0.5, Hf: 0.02-0.1, Y: 0.02-0.1, Mg: max. 0.1, Ti: max. 0.02, Zr: max. 0.09, SE: max. 0.02, Sr: max. 0.1, Ca: max: 0.1, Cu: max. 0.5 V: max. 0.1 Ta: max. 0.1, Nb: max. 0.1,C: max. 0.03, N: max. 0.01, B: max. 0.01, The residue consists of iron and impurities caused by the melting process.
(FR) L'invention concerne un alliage ferritique, résistant à l'oxydation, constitué de fer-chrome-aluminium-ytrium-hafnium, pour la réalisation de feuilles minces et de fils, présentant une durée de vie plus longue et une vitesse d'oxydation réduite à des températures élevées, une résistance élevée à la traction à chaud et une résistance électrique spécifique élevée. La composition de cet alliage (en % en masse) est la suivante: Cr: 16-22, Al: 6-10, Si: 0,02-1,0, Mn: max. 0,5, Hf: 0,02-0,1, Y: 0,02-0,1, Mg: max. 0,1, Ti: max. 0,02, Zr: max. 0,09, SE: max. 0,02, Sr: max. 0,1, Ca: max. 0,1, Cu: max. 0,5, V: max. 0,1, Ta: max. 0,1, Nb: max. 0,1, C: max. 0,03, N: max. 0,01, B: max. 0,01, le reste étant constitué de fer et des impuretés résultant de la fusion.
(DE) Ferritische oxidationsbeständige Eisen-Chrom-Aluminium-Yttrium-Hafnium-Legierung für dünne Folien und Drähte mit verbesserten Lebensdauer und einer reduzierten Oxidationsgeschwindigkeit bei hohen Temperaturen, einer hohen Warmzugfestigkeit und einem hohen spezifischen elektrischen Widerstand mit folgender Zusammensetzung (Masse %): Cr: 16-22, A1: 6-10, Si: 0,02-1,0, Mn: max. 0,5, Hf: 0,02-0,1, Y: 0,02-0,1, Mg: max. 0,1, Ti: max. 0,02, Zr: max. 0,09, SE: max. 0,02, Sr: max. 0,1, Ca: max: 0,1, Cu: max. 0,5 V: max. 0,1 Ta: max. 0,1, Nb: max. 0,1, C: max. 0,03, N: max. 0,01, B: max. 0,01, Rest Eisen sowie erschmelzungsbedingte Verunreinigungen.
