Nun war es zwar an sich bekannt, dass die Anlassbeständigkeit von Stählen durch Zusatz von Vanadium erhöht werden kann.
Eine so hohe Anlassbeständigkeit war aber bei den gemäss der Erfindung zu verwendenden wolfram-, molybdänund kobaltfreien Chrom-Vanadium-Stählen nicht zu erwarten, zumal die bekannten Warmarbeitsstähle nur bis zu 0#5% Vanadium enthalten. So wird z. B. die Festigkeit eines bekannten Warmarheitsstahles mit etwa 0-45% Kohlenstoff, etwa
EMI1.2
den anmeldungsgemässen Stählen bei einer Anlasstemperatur von 400 C bereits um 12 kg/mm2 und bei einer Anlasstemperatur von 600 C sogar um 44 kg/mm2 übertroffen.
Sämtliche erfindungsgemäss zu verwendenden Stähle sind leicht schmiedbar und im geglühten Zustand gut bearbeitbar. Um eine Verarmung der Grundmasse an Kohlenstoff zu vermeiden, erscheint es zweckmässig, mit steigendem Vanadiumgehalt auch den Kohlenstoffgehalt innerhalb der angegebenen Grenzen zu erhöhen.

Now it was known that the tempering resistance of steels can be increased by adding vanadium.
Such a high tempering resistance was not to be expected with the tungsten, molybdenum and cobalt-free chrome-vanadium steels to be used according to the invention, especially since the known hot-work steels only contain up to 0-5% vanadium. So z. B. the strength of a known high-temperature steel with about 0-45% carbon, about
EMI1.2
the steels according to the application are already exceeded by 12 kg / mm2 at a tempering temperature of 400 C and even by 44 kg / mm2 at a tempering temperature of 600 C
All steels to be used according to the invention are easy to forge and can be easily machined in the annealed state. In order to avoid a depletion of the basic mass of carbon, it appears expedient to increase the carbon content within the specified limits as the vanadium content increases.
