EMI1.1
Den Gegenstand vorliegender Erfindung bildet eine Stahllegierung für einen besonderen Anwendungszweck, der mehrere bestimmte Eigenschaften gleichzeitig verlangt ; die Kennzeichen dieser Stahllegierung bestehen in eingeengten GewichtsintervaUen der Zusätze, die in weiteren Grenzen für andere Verwendungsgebiete bereits bekannt sind.
Z. B. wird für gewisse Verwendungszwecke, wie Stehbolzenbohrer, Gewindebohrer, Kaliber usw.. ein Stahl benötigt, der durch das Härten möglichst wenig und möglichst gleichmässig seine Länge ändert und an dem sich im ungehärteten Zustand, selbst bei hohen Schnittgese@windigkeiten, reine Gewinde herstellen lassen.
EMI1.2
Die ersteren und die niedrig legierten Chromstähle entsprechen der Anforderung geringer und gleichmässiger Längenänderung beim Härten, haben aber den Nachteil, dass sie bei hohen Schnittgeschwindigkeiten unreines Gewinde ergeben und ausserdem ein enges Härtetemperaturintervau besitzen.
Die hochlegierten Chromstähle dagegen lassen sich bei hoher Geschwindigkeit rein schneiden und verhalten sich in b'ezug auf Änderung der Abmessungen beim Härten gut. Ein Nachteil letzterer Stähle ist aber, dass sie sehr spröde und sehr teuer sind.
Gegenstand der Erfindung ist nun eine Mangan-Chrom-Wolfram-Stahllegierung, die alle drei geforderten Eigenschaften vereinigt, indem sie ]. beim Härten ihre Länge weniger und gleichmässiger ändert als die bereits bekannten Stähle,
2. bei erhöhter Geschwindigkeit sich sauber bearbeiten lässt und
3. trotz guter Schneidfähigkeit sowohl in geglühtem wie in gehärtetem Zustand zäher ist, als die anderen obgenannten Stah11egierungen.
Ausserdem hat dieser Stahl den Vorteil eines weiten Härtetemperaturintervalles.
EMI1.3
Chrom, 1-73% Wolfram, 0-34% Silizium, Rest Eisen.
PATENT-ANSPRÜCHE :
1. Stahllegierung für Werkzeuge, die sich beim Härten in der Länge möglichst wenig und gleichmässig ändern sollen, mit 0. 7-1. 5% Kohlenstoff, 0#7-2% Mangan, 0#-2% Chrom, 0. 8-2% Wolfram und 0-1% Silizium.

EMI1.1
The subject of the present invention is a steel alloy for a particular application which requires several specific properties at the same time; The characteristics of this steel alloy consist in the restricted weight intervals of the additives, which are already known within broad limits for other areas of application.
For example, for certain purposes, such as stud drills, taps, calibers, etc., a steel is required that changes its length as little and as uniformly as possible through hardening and on which pure threads can be produced in the unhardened state, even with high cutting angles .
EMI1.2
The former and the low-alloy chrome steels meet the requirement of a small and even change in length during hardening, but have the disadvantage that they result in impure threads at high cutting speeds and also have a narrow hardening temperature interval.
The high-alloy chrome steels, on the other hand, can be cut clean at high speed and behave well with regard to changes in dimensions during hardening. However, a disadvantage of the latter steels is that they are very brittle and very expensive.
The invention now relates to a manganese-chromium-tungsten steel alloy which combines all three required properties by]. when hardening their length changes less and more evenly than the already known steels,
2. Can be processed cleanly at increased speed and
3. Despite good cutting properties, it is tougher in both the annealed and hardened condition than the other steel alloys mentioned above.
In addition, this steel has the advantage of a wide hardening temperature range.
EMI1.3
Chromium, 1-73% tungsten, 0-34% silicon, the remainder iron.
PATENT CLAIMS:
1. Steel alloy for tools that should change their length as little and evenly as possible during hardening, with 0. 7-1. 5% carbon, 0 # 7-2% manganese, 0 # -2% chromium, 0.8-2% tungsten and 0-1% silicon.
