Description

Herstellung von Gegenständen, die in den Randschichten durch Versticken gehärtet sind :Ulan hat zur Herstellung von Gegenständen, die in den Randschichten durch Versticken bei einer Temperatur von weniger als 58o° C gehärtet sind, bereits Stahllegierungen in Vorschlag gebracht die Aluminium, Chrom, Mangan oder Silicium einzeln oder in beliebiger Zusammensetzung enthalten. Die vorliegende Erfindung verfolgt den Zweck, der Technik eine weitere Gruppe von quaternären sowie komplexen Stahllegierungen an die Hand zu geben, die bei der Durchführung des an sich bekannten Verstickungsverfahrers in den Randzonen große Härte annehmen und sich im übrigen durch besonders gute Festigkeitseigenschaften (insbesondere Zähigkeit und Unempfindlichkeit gegen Anlaßsprödigkeit) sowie durch Vergütbarkeit in großen Querschnitten auszeichnen. Dieser Zweck wird der Erfindung gemäß dadurch erreicht, daß zur Herstellung der eingangs genannten Gegenstände Stahllegierungen verwendet werden, die einzeln oder in beliebiger Zusammenstellung i bis 8 "/" Silicium, Mangan, Nickel, Chrom, Molybdän, Wolfram, Vanadium, Titan oder Zirkon sowie weniger als o;5 "/" Aluminium und bis zu 0,7 "/" Kohlenstoff enthalten. Wenn der Gesamtgehalt an Silicium. Mangan, Nickel, Chrom, Molybdän, Wolfram, Vanadium, Titan oder Zirkon einzeln oder in beliebiger Zusammenstellung zwischen q, bis 8 "/" liegt, können vorteilhaft zur Herstellung der erwähnten Gegenstände auch solche Stahllegierungen verwendet werden, die o,5 bis 2,'4 Aluminium enthalten, und zwar empfiehlt es sich, den Aluminiumgehalt in den angegebenen Grenzen entsprechend dem Gesamtgehalt der übrigen Legierungskomponenten zu steigern.Manufacture of items in the outer layers by embroidering are hardened: Ulan has to manufacture objects that are in the outer layers are hardened by stitching at a temperature of less than 58o ° C Steel alloys brought into proposal include the aluminum, chromium, manganese or silicon contained individually or in any combination. The present invention The technology pursues another group of quaternary as well as complex To give steel alloys to the hand in the implementation of the known Verickungsverfahrers assume great hardness in the edge zones and otherwise due to particularly good strength properties (especially toughness and insensitivity against temper brittleness) as well as being able to be tempered in large cross-sections. This purpose is achieved according to the invention in that to produce the Steel alloys mentioned above are used individually or in any combination i to 8 "/" silicon, manganese, nickel, chromium, molybdenum, Tungsten, vanadium, titanium or zirconium as well as less than 0.5 "/" aluminum and up Contains 0.7 "/" of carbon. When the total content of silicon. Manganese, nickel, Chromium, molybdenum, tungsten, vanadium, titanium or zirconium individually or in any Composition between q, up to 8 "/", can be advantageous for the production of the items mentioned, those steel alloys are also used that o, 5 to 2, '4 contain aluminum, and although it is recommended that the aluminum content in the specified limits according to the total content of the remaining alloy components to increase.

Die Legierungen selbst sind ihrer stofflichen Zusammensetzung nach nicht Gegenstand der Erfindung.The alloys themselves are based on their material composition not the subject of the invention.
