Description
<Desc/Clms Page number 1>
Nickelchromstahl, insbesondere für Panzerplatten.
Seit einigen Jahren ist es Gebrauch bei der Herstellung von Panzerplatten geworden, Platten aus einem Stahl herzustellen, der im wesentlichen etwa die folgende Zusammen- setzung besitzt :
EMI1.1
<tb>
<tb> Kohlenstoff <SEP> 0'280/0
<tb> Mangan <SEP> 0'35"/
<tb> Nickel, <SEP> 3-75%
<tb> Chrom.......... <SEP> 1-70%
<tb>
Der Schwefel und Siliziumgehalt ist niedrig, unter 0'040/0'Ein Stahl dieser Zusammensetzung wird nach den Verfahren von Harvey oder Krupp behandelt, wodurch seine Oberfläche stark gekohlt wird, zum Zwecke, sie widerstandsfähiger gegen das Auftreffen von Geschossen zu machen. Während nun die Zementierung die Oberfläche verbessert, ist sie nachteilig in ihrer Wirkung auf den Körper der Platte.
Es ist nun. eine neue Stahllegierung gefunden worden, die bei einer besonderen Behandlung es ermöglicht, Panzerplatten und Deckschutzplatten von homogener chemischer Zusammensetzung zu schaffen, ohne die Notwendigkeit, die Oberfläche zu zementieren ; die neue Platte gibt bessere Ergebnisse in bezug auf die Widerstandsfähigkeit gegen das Auftreffen von Geschossen, als bisher erreicht worden sind. Es sei hier bemerkt, dass natürlich schon Stahllegierungen zur Herstellung von Panzerplatten angegeben worden sind, bei denen ein Zementieren nicht erforderlich ist.
Der Stahl gemäss der Erfindung kennzeichnet sich gegenüber den bekannten Chrom- nicke ! stählen durch geringen Kohlenstoff-und Chromgehalt und hohen Nickelgehalt, und zwar enthält derselbe :
EMI1.2
<tb>
<tb> Kohlenstoff <SEP> etwa <SEP> 0#15 <SEP> bis <SEP> 0#25%
<tb> Nickel <SEP> ...... <SEP> mehr <SEP> als <SEP> 7-00 <SEP> und <SEP> höchstens <SEP> etwa <SEP> 12#00%
<tb> Chrom. <SEP> etwa <SEP> bis <SEP> bis <SEP> 0-26%

Nickel chrome steel, especially for armor plates.
For some years now it has been used in the manufacture of armor plates to manufacture plates from a steel which essentially has the following composition:
EMI1.1
<tb>
<tb> carbon <SEP> 0'280 / 0
<tb> Manganese <SEP> 0'35 "/
<tb> Nickel, <SEP> 3-75%
<tb> Chromium .......... <SEP> 1-70%
<tb>
The sulfur and silicon content is low, below 0'040 / 0'.A steel of this composition is treated according to the methods of Harvey or Krupp, whereby its surface is strongly carbonized in order to make it more resistant to projectile impact. Now while the cementation improves the surface, it is detrimental in its effect on the body of the plate.
It is now. a new steel alloy has been found which, with a special treatment, makes it possible to create armor plates and protective cover plates of homogeneous chemical composition without the need to cement the surface; the new plate gives better results in terms of bullet impact resistance than has previously been achieved. It should be noted here that steel alloys have of course already been specified for the production of armor plates, which do not require cementing.
The steel according to the invention is different from the known chrome nicks! steels with low carbon and chromium content and high nickel content, namely the same contains:
EMI1.2
<tb>
<tb> carbon <SEP> about <SEP> 0 # 15 <SEP> to <SEP> 0 # 25%
<tb> Nickel <SEP> ...... <SEP> more <SEP> than <SEP> 7-00 <SEP> and <SEP> at most <SEP> about <SEP> 12 # 00%
<tb> chrome. <SEP> about <SEP> to <SEP> to <SEP> 0-26%
<tb>
EMI1.3
