Description
Nickelfreier Spezialstahl. Früher wurden Stahllegierungen mit 7- bis 8 Prozent Ni oder solche mit 7 bis 8 Prozent Ni und geringen Zusätzen von Co, und Mo, oder Stahle mit q. bis 5 Prozent N i und i bis 2 Prozent Si dazu verwendet, Schutzchilde aller Art, Helme, Sturmkappen, Geschützrohrmaterial und überhaupt Gegenstände, bei denen neben hoher Festigkeit und Härte hohe Zähigkeit verlangt wird, z. B. hochwertige Baustähle für die -Automobil- und Flugzeugindustrie, herzustellen. Später während des Krieges wurden vielfach nickelfreie Stahllegierungen für diese Zwecke vorgeschlagen, die sehr gute Eigenschaften hatten, die aber trotzdem dem Nickelstahl nicht ganz gleichwertig waren.Nickel-free special steel. Steel alloys with 7- to 8 percent Ni or those with 7 to 8 percent Ni and small additions of Co, and Mo, or steels with q. up to 5 percent Ni and i up to 2 percent Si are used Protective shields of all kinds, helmets, storm caps, gun barrel material and objects in general, where, in addition to high strength and hardness, high toughness is required, e.g. B. high quality Manufacture structural steels for the automotive and aircraft industries. Later during During the war, nickel-free steel alloys were often proposed for these purposes, which had very good properties, but which were still not quite like nickel steel were equivalent.
Es ist ferner der Erfinderin eine Stahllegierung geschützt, die o,32 bis 0,4.8 C, i bis 2 Mn, 0,5 bis 1,5 Si und bis 2 Prozent Mo enthält. Diese nickelfreie Stahllegierung kommt in ihren Eigenschaften den Nickelstählen nahe. Weitere Versuche mit dieser Legierung haben nun zu einer Abänderung der Zusammensetzung geführt, die den früheren Nickelstählen voll und ganz gleichwertig ist. Diese Versuche haben ergeben, daß man mit den Niedrigstgrenzen wesentlich heruntergehen kann, wenn gleichzeitig der Si-Gehalt erhöht wird. Man kann gegenüber der geschützten Legierung bis auf C = o,2o Mn = o,5 und Mo = 0,5 herabgehen, wenn Si bis auf 2,5 Prozent erhöht wird; dabei kann das Mo durch i bis 4: Prozent Wo ganz oder teilweise ersetzt werden.It is also protected by the inventor a steel alloy, the o, 32 to 0.4.8 C, i to 2 Mn, 0.5 to 1.5 Si and up to 2 percent Mo. This nickel free Steel alloy comes close to nickel steels in terms of its properties. More attempts with this alloy have now led to a change in the composition, which is fully equivalent to the earlier nickel steels. Have these attempts show that you can go down significantly with the lowest limits if at the same time the Si content is increased. You can up to the protected alloy C = 0.2o, Mn = 0.5 and Mo = 0.5 decrease as Si is increased to 2.5 percent; Mo can be replaced in whole or in part by i to 4: percent Wo.
