Abstract : The purpose of this investigation was to determine the ballistic properties of a face hardened tungsten steel armor plate. Armor plate containing .235% C, 3.36% W, .62% Cr, .20% V, after carburizing and proper heat treatment, resisted penetration with highest practicable velocities, Cal. .30 A.P., M1922, 2700 f.s. at 100 yards. The ballistic limit of this plate, using Cal. .50 A.P., M1 ammunition, was 2057 f.s. No spalling resulted from firing at the plate.
