Abstract : In response to a request of the Office, Chief of Ordnance, a general program of development armor component materials is being conducted at this arsenal. As part of this program tests have recently been completed on samples of NE-8620 steel supplied by the Republic Steel Corporation. Although the resistance of none of these samples to perforation by cal. .45 steel-jacketed ball projectiles was comparable with that of an equivalent weight of Hadfield manganese steel, samples tested in the as-quenched condition exhibited resistance characteristics superior to those of the tempered specimens.
