  Zum Härten durch Versticken bestimmter Ofen. 



   Die Erfindung bezweckt, einen Härteofen zu schaffen, der für die Durchführung der Nitrierhärtung besonders geeignet ist. Zu diesem Zwecke werden die mit den Nitriergasen in Berührung kommenden Teile des Ofens aus einer die katalytische Zersetzung der Gase verhindernden Legierung, insbesondere einer nichtrostenden und gegen den Angriff durch Säuren beständigen Stahllegierung, hergestellt. Die chemisch neutralen   Chrom-und Chromniekelstahllegierungen   eignen sich hiefür in besonderem Masse, weil sie ausser der geforderten Eigenschaft, keinen schädlichen Einfluss auf die Nitriergase auszuüben, auch noch ihrerseits widerstandsfähig gegen den Angriff der heissen Gase sind.

  Furnaces designed for hardening by stitching.



   The aim of the invention is to create a hardening furnace which is particularly suitable for carrying out nitriding. For this purpose, the parts of the furnace that come into contact with the nitriding gases are made of an alloy that prevents the catalytic decomposition of the gases, in particular a stainless steel alloy that is resistant to attack by acids. The chemically neutral chromium and stainless steel alloys are particularly suitable for this because, in addition to the required property of not exerting any harmful influence on the nitriding gases, they are in turn resistant to attack by the hot gases.
