legiert wird. Diese Stähle bezeichnet man als Chrom-Wolfram-Stähle.
Es ist bekannt, derartigem Stahl auch noch geringe Mengen Vanadium, Molybdän und dgl. zuzusetzen. Sie heissen dann z. B. Chrom-Wolfram-Molybdän-Stähle. Wird diesem bekannterweise ausserdem ein Zusatz von grösseren Mengen Kobalt gemacht, so erhält man dieChrom-Wolfram-Kobalt-Stähle.
Versuche haben nun ergeben, dass es möglich ist, bei einem über 04 bis zu 20/0 gesteigerten Mangangehalt und etwas höherem Chromgehalt auf den Zusatz von Molybdän zu verzichten, wenn man genügend Kobalt, d. h. zwischen 1 bis 5%, zusetzt. Dadurch

ein Unbrauehbarworden des Stahles herbeigeführt wird. Auch kann in gewissem Sinne ein Weniger des einen Elementes durch ein Mehr eines anderen ersetzt werden.
Der vorliegende Chrom-Kobalt-Stahl kann in seiner Arbeitsleistung als Schnellarbeitsstahl (lurch einen Zusatz von bis zu 20 0 Vanadium besonders bezüglich der Schnitthaltigkeit nennenswert verbessert werden. Dadurch entsteht alsdann ein Chrom-Kobalt-Vanadium-Stahl.

is alloyed. These steels are known as chrome-tungsten steels.
It is known to add small amounts of vanadium, molybdenum and the like to such steel. They are then called z. B. Chromium-tungsten-molybdenum steels. If, as is well known, larger amounts of cobalt are added to this, then the chromium-tungsten-cobalt steels are obtained.
Tests have now shown that it is possible to dispense with the addition of molybdenum if the manganese content is increased above 04 to 20/0 and the chromium content is slightly higher, if there is enough cobalt, i.e. H. between 1 to 5%, added. Thereby
EMI1.2
the steel is made unbearable. In a certain sense, less of one element can also be replaced by more of another.
The present chromium-cobalt steel can be significantly improved in its work performance as high-speed steel (by adding up to 20 0 vanadium, especially with regard to the edge retention. This then results in a chromium-cobalt-vanadium steel.
