In accordance with a request of the Office, Chief of Ordnance, a program of development of improved body armor components was conducted at this arsenal. As apart of this program tests have recently been concluded on samples of an austenitic steel, in various conditions of hardness, supplied by Jessop Steel Company. The resistance of the as-annealed sample to perforation by cal. . 45 steel-jacketed projectiles was superior to that of the hardened samples. The resistance of the 14 Hard sample to perforation by the cal. .22 fragment- simulator appears to be superior to that of the others although the gauge variation between the samples renders precise evaluation difficult. The resistance of all samples of this steel is considerably inferior to that of an equivalent weight of Hadfield manganese steel.
