Effect of Hardness on Resistance of a Thin-Gauge (.039 to .042 in.) Modified SAE 4340 Steel to Perforation by Fragment-Simulating Projectiles

Abstract

In conjunction with a program of development of improved body armor components, tests have recently been completed on samples of a modified SAE 4340 steel in three conditions of hardness. Samples of each condition of hardness were clamped rigidly to a wooden ballistic frame which allows an 8 inch x 8 inch area to remain unsupported from the rear and impacts of caliber .45 ball projectiles and three types of fragment-simulating projectiles developed at this arsenal were directed into these areas.
