Abstract : Tests were conducted at this arsenal on samples of light-gauge (about .045 inch) SAE-X4130 steel and NE-8630 steel as-rolled and after heat treatment. Heat treatment effected a substantial improvement in the resistance characteristics of both types of steel, although the resistance of an equivalent weight of Hadfield manganese steel is still superior to that of the heat-treated samples. One sample of each was subjected to fire with caliber .45 steel-jacketed ball projectile.
