Description

Schußwaffenrohre Es ist bekannt, Stahllegierungen, die o,o5 bis 1,3 % Kohlenstoff, mehr als 3 und weniger ,als i i,5 % Chrom und o,5 bis 8 % Silicium enthalten, zur Herstellung von Geschützfuttern zu verwenden. Es sind ,auch warmfeste Stahllegierungen mit 7 bis io olo Wolfram, o,8 bis 3 % Silicium und gegebenenfalls bis zu 0,5 % Chrom sowie solche mit etwa 0,5 % Molybdän, etwa 2 % Silicium und bis zu 2 % Chrom bekannt. Ferner ist es bekannt, d:aß Vanadium oder Molybdän enthaltende Stahle, wenn sie diese Elemente im wesentlichen im Ferrit gelöst enthalten, eine hohe Dauerstandfestigkeit aufweisen. Es ist jedoch noch nicht vorgeschlagen worden, Schußwaffenrohre aus den nach der Erfindung verwendeten Stahllegierungen herzustellen.Firearm barrels It is known to use steel alloys which contain 0.05 to 1.3 % carbon, more than 3 and less than 1.5% chromium and 0.5 to 8% silicon for the production of gun linings. There are also heat-resistant steel alloys with 7 to 10% tungsten, 0.8 to 3% silicon and optionally up to 0.5% chromium and those with about 0.5% molybdenum, about 2% silicon and up to 2% chromium known . It is also known that steels containing vanadium or molybdenum, if they contain these elements essentially dissolved in the ferrite, have a high fatigue strength. However, it has not yet been proposed to manufacture gun barrels from the steel alloys used in accordance with the invention.

Den Gegenstand der Erfindung bildet die Verwendung solcher Stähle zur Herstellung von Rohren für Schußwaffen (Handfeuerwaffen, Geschütze jeder Art), die neben etwa 0,7 bis 2,5 % Silicium noch i bis 5 % Chrom und gleichzeitig mindestens o, i % von einem oder mehreren der carbidbildenden Elemente Wolfram, Molybdän, Vanadium, Titan, Tantal enthalten, wobei der Gehalt an Chrom und den weiteren carbidbildenden Elementen insgesamt bis zu io % beträgt. Rohre der angegebenen Art bewähren sich nämlich ausgezeichnet ,gegenüber de:n korrodierenden und explosionsartigen Beanspruchungen, wie sie beim Betrieb der oben angegebenen Gegenstände auftreten. Als besonders ,geeignet hat sich die Verwendung von Stahllegierungen erwiesen, die etwa 0,2 bis o,8 % Kohlenstoff, 0,7 bis 2,5 % Silicium und 1,2 bis 5 0/0 Chrom sowie 0,15 bis I % Molybdän, o, i bis i % Vanadium, o,5 bis 4 % Wolfram, einzeln: oder ,gemischt enthalten oder im besonderen etwa o,5 % Kohlenstoff, 45 % Silicium, 1,5 % Chrom, 0,3 % Molybdän und 0,2 % Vanadium aufweisen.The subject of the invention is the use of such steels for the production of tubes for firearms (handguns, guns of all kinds), which in addition to about 0.7 to 2.5% silicon still i to 5% chromium and at the same time at least o, i% of one or more of the carbide-forming elements tungsten, molybdenum, vanadium, Titanium, tantalum contain, the content of chromium and the other carbide-forming Elements total up to io%. Pipes of the specified type prove themselves namely excellent, against the: n corrosive and explosive stresses, as they occur during the operation of the items specified above. As particularly, suitable the use of steel alloys has been shown to contain about 0.2 to 0.8% carbon, 0.7 to 2.5% silicon and 1.2 to 5% chromium and 0.15 to 1% molybdenum, o, i up to i% vanadium, 0.5 to 4% tungsten, individually: or, mixed or contained in especially about 0.5% carbon, 45% silicon, 1.5% chromium, 0.3% molybdenum and 0.2% vanadium.

Die angegebenen Stähle können vergütet werden, um Festigkeit, Streckgrenze usrv. im gewünschten Sinne zu beeinflussen.The specified steels can be quenched and tempered for strength and yield strength usrv. to influence in the desired sense.
