Tests have recently been conducted at this arsenal on one type of Monel Metal and two types of high-nickel alloys in various conditions of hardness as supplied by the International Nickel Company. The resistance of none of these samples to perforation by cal. .45 steel-jacketed ball projectiles or by cal. .22 fragment simulating projectiles, G-22, was comparable with that of an equivalent weight of Hadfield manganese steel. In general, the resistance of the softer specimens of a given alloy whose hardnesses had been developed by the same process tended to be superior to that of the harder specimens of the same type.
