Description
Schnelldrehstähle mit erhöhter Warmfestigkeit@und Schneidhaltigkeit Um Legierungsmetalle zu sparen, wurden bisher schon verschiedene Wege versucht, z. B. die Beilegierung von Stickstoff.High-speed steels with increased heat resistance @ and edge retention In order to save alloy metals, various ways have been tried so far: z. B. the addition of nitrogen.
Überraschenderweise wurde nun gefunden, daß Schneidhaltigkeit und Warmfestigkeit bei Schnelldrehstählen dadurch gesteigert werden können, daß man Schnelldrehstählen Stickstoff in Form schwerlöslicher Nitride zusetzt, wofür die Nitride des Titans und Zirkons in Frage kommen. Die Nitride brauchen nur in geringer Menge vorhanden zu sein, um Warmfestigkeit und Schneidhaltigkeit der Stähle zu erhöhen.Surprisingly, it has now been found that edge retention and Heat resistance in high-speed steels can be increased by High-speed steels add nitrogen in the form of sparingly soluble nitrides, for which the Nitrides of titanium and zirconium come into question. The nitrides only need a little Amount to be present in order to increase the high temperature strength and edge retention of the steels.
Man kann zur Bildung der geringen Mengen an schwerlöslichen Nitriden dem Stahlbad das Titan oder Zirkon zusetzen und dann ein Nitrid, wie Chrom- oder Eisennitrid, hinzufügen oder in das Stahlbad den Stickstoff vorher in Form von Chrom-oder Eisennitrid einbringen und dann durch späteren Zusatz von Titan und/oder Zirkon die schwerlöslichen Nitride bilden; praktisch kommen hierfür Gehalte von 0,02 bis o,i % Stickstoff, der in den schwerlöslichen Nitriden gebunden ist, in Betracht.One can to the formation of the small amounts of sparingly soluble nitrides add the titanium or zirconium to the steel bath and then a nitride, such as chromium or Iron nitride, add or in the steel bath the nitrogen beforehand in the form of chromium or Introduce iron nitride and then later add titanium and / or zirconium form the sparingly soluble nitrides; in practice, levels of 0.02 to 0.1% nitrogen bound in the sparingly soluble nitrides into consideration.
Dadurch gelingt es, einen Schnelldrehstahl mit z. B. r % Kohlenstoff, 4°/o Chrom, 2,2% Vanadin und 2,50/0 Molybdän auf die Leistung eines Stahles zu heben, der außerdem noch 2,5% Wolfram enthält. Damit ist also praktisch das Wolfram zur Gänze ersetzbar.This makes it possible to use a high-speed steel with z. B. r% carbon, 4% chromium, 2.2% vanadium and 2.50 / 0 molybdenum to raise the performance of a steel, which also contains 2.5% tungsten. So that's practically the tungsten for Completely replaceable.
Durch Zusatz schwerlöslicher Nitride kann man auch Schnelldrehstähle mit höheren Wolframgehalten in ihrer Leistung steigern.High-speed steels can also be made by adding sparingly soluble nitrides increase their performance with higher tungsten contents.
