Description

Verwendung von Eisen-Chrom-Legierungen für magnetisch: beanspruchte Gegenstände Den Gegenstand des Patents 731 409 bildet die Verwendung von Eisen-Chrom-Legierungen mit mehr als i o o/o, bis 4o % Chrom, Rest Eisen mit etwaigen üblichen Verunreinigungen, als Werkstoff für solche magnetisch beanspruchten Gegenstände, die eine hohe Anfangspermeabilität und gegebenen- falls geringe Wirbelsitromverluste aufweisen müssen, insbesondere der Hochfrequenztechnik. Es hat sich nun gezeigt, daß in den nach dem Hauptpatent verwendeten Leegierungen das Chrom teilweesie durch Molybd;än oder Wolfram oder beide mit der Maßgabie ersetzt werden kann, .da3 die Summe der vorgenannten Legierungsielemente mehr als i o %, bis zu 400/0 bjeträ;gt. Diese L.egileru@ngen können ehenso wie die nach dem Hauptpatent Ver- wendeten noch bis zu i o o/o Silizium: oder Alun@inium einzeln oder zusammen @e!nithalten. Der Kohlenstoff- gehalt beträgt vorzugsweise weniger als 0,30/0 und der Mang angehalt weniger als 2%. Dia Legierun- gen werden zweckmäßig einer Glühb;ehandlung unterworfen, die z. B. bei goo° im Schutzgas kann. Use of iron-chromium alloys for objects subject to magnetic loads The subject of the patent 731 409 forms the Use of iron-chromium alloys with more than 100%, up to 40% chromium, the remainder iron with any usual impurities, as a material for such magnetically stressed objects, which have a high initial permeability and if they have to show minor losses from the vertebral currents, especially high frequency technology. It has now been shown that in the after The main patent alloys used chrome partly by molybdenum or tungsten or both can be replaced with the measure, .da3 the Sum of the aforementioned alloy elements more as io%, up to 400/0 by weight This L.egileru@ngen can as well as those according to the main patent still used up to 100 / o silicon: or aluminum individually or together @e! The carbon content is preferably less than 0.30 / 0 and the Mang stopped less than 2%. D i a alloy genes become expedient to an incandescent act subject to the z. B. at goo ° in the protective gas can.
