Description
Stahllegierung für Werkzeuge. Während Nickel schon seit langem als Legierungselement für Baustähle, denen es neben guter Bearbeitbarkeit und grosser Zä higkeit vorzügliche Festigkeitseigenschaften verleiht, verwendet wird, ist es bisher noch nicht gelungen, diese vorzüglichen Eigen schaften des Nickels den Werkzeugstählen zu Nutze zu machen, wo sie insbesondere bei Werkzeugen für Kaltschlagarbeit, die eine grosse Aussenhärte besitzen müssen und daher Wasserhärtung bedingen. verlangt wer den, weil das Nickel in Gegenwart von etwas höheren Kohlenstoffgehalten den Werkzeug stahl spröde und feuerempfindlich macht.
Auf Grund eingehender Vesuche ist es nun gelungen, einen nickellegierten Werk zeugstahl herzustellen, der die vorerwähnten nachteiligen Erscheinungen nicht aufweist.
Cemäss der vorliegenden Erfindung wird dies dadurch bewerkstelligt, dass einem Werk- zeugstahl von etwa 0,6 bis 1,5 % Kohlenstoff- gehalt und 0.5 bis <B>8</B> 0'" Nickel,
1 bia <I>5</I> % min- destens eines härtend wirkenden, aber nicht spröde machenden kTetalles hinzugefügt wird. Dadurch wird ein Stahl gewonnen, der Härte mit grosser Zähigkeit verbindet, im Wasser gehärtet werden kann und auch gegen Über hitzung nicht empfindlich ist. Ein solcher Stahl leistet besonders bei Kaltschlagarbeit ausgezeichnete Dienste.
Die Zusammensetzung des Stahles bewegt sich zum Beispiel in fol- genden Grenzen: nur 0,6 bis 1,5 % C, 0,5 bis 3 % Ni, 1 bis 5 % Wo. Das Wolfram, kann dabei ganz oder teilweise durch Vanadin ersetzt werden,
nicht aber durch IYIolybdän oder Chrom. Besonders das letztere Metall würde den Stahl zu spröde machen und würde eine Wasserhärtung vollkommen ausschliessen. Ausserdem haben Chromniclielstähle noch den Nachteil der Anlasssprödigkeit.
Steel alloy for tools. While nickel has long been used as an alloying element for structural steels, which, in addition to good machinability and great toughness, it gives excellent strength properties, it has not yet been possible to make use of these excellent properties of nickel in tool steels, where they are particularly useful Tools for cold impact work that must have a high degree of external hardness and therefore require water hardness. Whoever is required because, in the presence of slightly higher carbon contents, the nickel makes the tool steel brittle and sensitive to fire.
On the basis of detailed tests, it has now been possible to produce a nickel alloy tool steel that does not have the aforementioned disadvantageous phenomena.
According to the present invention, this is achieved in that a tool steel with about 0.6 to 1.5% carbon content and 0.5 to 8 0 '"nickel,
1 bia <I> 5 </I>% at least one hardening, but not embrittling, ketal is added. As a result, a steel is obtained that combines hardness with great toughness, can be hardened in water and is not sensitive to overheating. Such a steel is particularly useful for cold impact work.
The composition of the steel moves, for example, within the following limits: only 0.6 to 1.5% C, 0.5 to 3% Ni, 1 to 5% Wo. The tungsten can be wholly or partially replaced by vanadium,
but not by molybdenum or chromium. The latter metal in particular would make the steel too brittle and would completely rule out water hardening. In addition, chromium-nickel steels have the disadvantage of being brittle.
