Resistance of Austempered Mn-Mo Steel to Perforation by Cal. .45 Steel- Jacketed Ball Projectiles
Abstract
As part of a program of development of improved body armor component materials, samples of a manganese-molybdenum steel austempered in a salt bath at different temperatures have recently been tested at this arsenal. Although a slight superiority in resistance to perforation by cal. .45 steel-jacketed ball projectiles is apparently attained by the sample austempered with agitation at 500 deg F when compared with samples austempered without agitation at 450, 500, 600 and 700 deg F, the general level of resistance is far below that of an equivalent weight of Hadfield manganese steel and is appreciably inferior to that of some other types of ferritic steels previously examined.
