Abstract: The U.S. Army Research Laboratory (ARL) and Australian Defence Science and Technology Organisation (DSTO) have ballistically baselined a range of armor steels (277-321HB to 477-534HB) manufactured by the Australian company, Bisalloy Steels. Plate was tested in thicknesses from 10 mm to 20 mm and ARL and DSTO ballistically tested the plates against 0.30 calibre and 0.50 calibre armor piercing projectiles, 0.50 calibre and 20 mm Fragment Simulating Projectiles (FSPs) and the 14.5 mm BS41. Ballistic performance was compared for armor steels over a range of hardnesses and toughnesses, and results compared with the minimum ballistic requirements of MIL-A-12560H and MIL-A-46100D.
