Summary:

The highest-performing U.S. steel alloys for armor-piercing (AP) bullet protection are manufactured to MIL-DTL-46100E, high-hardness armor (HHA) with a hardness range of 477-534 Brinell hardness number (BHN), and to MIL-A-46099C, dual hardness armor (DHA), which is produced by roll bonding a 601-712 BHN front plate to a 461-534 BHN back plate. While these materials still serve their intended applications, monolithic ultra-high-hardness (UHH) steels with a hardness of 600 BHN or greater have been developed. This class of steels increases AP bullet defeat, reduces armor weight, and eliminates the manufacturing difficulties inherent in DHA. Swedish Steel Oxelösund AB (SSAB) produces a number of grades of steel, which have previously been assessed against AP ammunition. However, SSAB has two UHH armor steels designated ARMOX ADVANCE has a nominal hardness of Rockwell C58-63 (>650 BHN). This report assesses the performance of these steels against two projectiles that will be used to generate a new military specification for UHH steel armor. The performance of these UHH steels will be compared to the current HHA MIL-DTL-46100E specification.
