Resistance of Light-Gauge Si-Ni-Cr-Mo and Cr-Mo-V Steels to Perforation by Fragment-Simulating Projectiles

摘要

As part of a program of development of improved study armor components requested by the Office, Chief of Ordnance, there have been conducted at this arsenal several investigations of heat-treatable steels as possible substitutes for the Hadfield manganese steel currently used. In conjunction with this phase of the program samples of a Si-Ni-Cr-Mo steel and of a Cr-Mo-V steel were heat treted variously and subjected to ballistic test. The resistance of all samples, however, was considerably inferior to that of Hadfield manganese steel of the same weight.
