Description

Verfahren zur Erhöhung der Schnitthaltigkeit von mit Cer und Vanadium legiertem Werkzeugstahl, insbesondere Schnellarbeitsstahl Es ist bekannt, zu Werkzeugstählen, die im allgemeinen außer Kohlenstoff noch Wolfram, Chrom, Molybdän oder mehrere dieser Elemente enthalten, Vanadium, Kobalt, Zirkon, Titan und Cer zur Verbesserung ihrer Eigenschaften zuzusetzen.Process for increasing the edge retention of cerium and vanadium Alloyed tool steel, especially high-speed steel It is known to tool steels, which in general besides carbon also tungsten, chromium, molybdenum or more These elements contain vanadium, cobalt, zircon, titanium and cerium for enhancement to add to their properties.

Erfindungsgemäß wird durch Zusatz von Cer und Vanadium, und zwar so, daß sich im Fertigerzeugnis Cer : Vanadium wie .i : 3 bis r : 5 verhalten, eine erhebliche Steigerung der Schnitthaltigkeit erreicht. Eine erhöhte Schnitthaltigkeit ist bereits zu verzeichnen, wenn hierbei der Cergehalt o,i bis 0,5 % beträgt. Versuche haben ergeben, daß ein Chrom-Wolfram-Schnellarbeitsstahl durch den gleichzeitigen Zusatz von Cer und Vanadium im Verhältnis von etwa i : 3, unter den gleichen Bedingungen geprüft, eine Erhöhung der Schnitthaltigkeit von 1o auf 23 Min. zeigte. Bei einem anderen Beispiel, bei welchem der Cergehalt etwa 1f5 des Vanadiumgehaltes ausmachte, wurde die Dauer der Schnitthaltigkeit von 23 auf 5o Min. erhöht.According to the invention, by adding cerium and vanadium in such a way that cerium: vanadium behaves like .i: 3 to r: 5 in the finished product, a considerable increase in edge retention is achieved. An increased edge retention is already recorded when the cerium content is 0.1 to 0.5 %. Tests have shown that a chromium-tungsten high-speed steel showed an increase in edge retention from 10 to 23 minutes through the simultaneous addition of cerium and vanadium in a ratio of about i: 3, tested under the same conditions. In another example, in which the cerium content was about 1f5 of the vanadium content, the duration of the edge retention was increased from 23 to 50 minutes.

Insbesondere werden solche Leistungssteigerungen dann erzielt, wenn die Stähle, insbesondere die Schnellarbeitsstähle, bei den üblichen Temperaturen angelassen werden.In particular, such performance increases are achieved when the steels, especially the high-speed steels, at the usual temperatures be left on.
