    Einseitig geh   irtete Panzerplatte.   



   Die Erfindung betrifft einseitig gehärtete Panzerplatten aus einer Stahllegierung mit etwa 0-2   bis 0#65% Kohlenstoff, 2 bis 4#5% Chrom, 0#2 bis 1#5% Molybdän und 0#5 bis 4% Nickel, deren Nickelgehalt   ganz oder zum Teil durch den   entsprechenden Kobaltgehalt   ersetzt ist. Wie üblich, kann man darin den   Molybdängehalt   ganz oder teilweise durch den 1-5 bis 3-fachen Wolframgehalt ersetzen. 
 EMI1.1 
 bei direkter Härtung als auch   bei Einsatzhärtung   erzielte grössere Zähigkeit der gehärteten Zone ergibt einen erhöhten Widerstand bei schlagähnlicher Beanspruchung, wie sie beim Beschuss durch Geschosse in Frage kommt. 



   Ein   Ausführungsbeispiel   stellt eine Panzerplatte von etwa 100 mm   Stärke mit 0-35% Kohlenstoff.   



  2-6% Chrom, 1-6% Kobalt und   0-4% Molybdän   dar. 



   Der Ersatz des Nickels durch Kobalt in einer Nickel-Molybdän- bzw. Nickel-Wolfram-Stahllegierung für Panzerplatten ist bekannt. Die Herstellung der   Panzerplatten   kann in üblicher Weise durch Walzen oder Giessen erfolgen.

    Armored plate hosted on one side.



   The invention relates to armor plates hardened on one side and made of a steel alloy with about 0-2 to 0 # 65% carbon, 2 to 4 # 5% chromium, 0 # 2 to 1 # 5% molybdenum and 0 # 5 to 4% nickel, the total nickel content of which or partially replaced by the corresponding cobalt content. As usual, the molybdenum content can be replaced in whole or in part by 1-5 to 3 times the tungsten content.
 EMI1.1
 Greater toughness of the hardened zone achieved with direct hardening as well as with case hardening results in increased resistance in the case of impact-like stress, such as is possible when bombarding with projectiles.



   One embodiment is an armor plate about 100 mm thick with 0-35% carbon.



  2-6% chromium, 1-6% cobalt and 0-4% molybdenum.



   The replacement of nickel by cobalt in a nickel-molybdenum or nickel-tungsten steel alloy for armor plates is known. The armor plates can be manufactured in the usual way by rolling or casting.
