Resistance of Light Gauge Mn-Mo Type Steel to Perforation by Standard Cal. .45 Ball Ammunition and by Fragment-Simulating Cal. .22 Projectile, G-2

Abstract

A program of development of improved body armor components is in progress at this arsenal. Samples of manganese-molybdenum type steel showed greater resistance to both types of projectiles in the 'as-quenched' condition than as tempered at 600 F., 700 F. or 800 F. In comparison with Hadfield manganese steel of the quality currently procurable under Specification AXS- 1170, the ballistic limit of the best samples of this steel (as-quenched) is about equivalent under impact of standard cal. .45 ball ammunition, only in the 0.50-in gauge, but is appreciably inferior under impact of the more significant cal .22 fragment-simulating projectile G-2 in all gauges.
