K is the revision number of the standard.) MIL-DTL-46177 is an older, now-replaced standard for a high hardness steel RHA. [4] It specifies a harder steel that is nearly identical to AR500 in terms of tensile and yield strength. [5] The Brinell hardness of AR500 is in the 477-534 range. MIL-DTL-46100E specifies a steel of identical hardness. [3]
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. [1]The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors.
Comparative testing of British 17-pounder (76 mm) gun and US Army APCBC rounds fired into captured German Panther tanks indicated the APCBC munitions were more accurate than late war armour-piercing discarding sabot (APDS) shot, though the lot used was described as sub-standard and the report made no determination of general APDS accuracy.

This committee worked four years, between 1861 and 1865, during which time it formulated the best performing armour with the metallurgy as then known, suggested ways for improving its production and quality and helped develop more effective shot against ironclad vessels. [19] For instance, two processes were used in constructing iron armour.
Liners have been made from many materials, including various metals [48] and glass. The deepest penetrations are achieved with a dense, ductile metal, and a very common choice has been copper . For some modern anti-armor weapons, molybdenum and pseudo-alloys of tungsten filler and copper binder (9:1, thus density is ≈18 Mg/m 3 ) have been ...
The propulsion system uses an obturating case base with a semi-combustible cartridge wall. It has a total weight of 41.1 lb (18.6 kg) and a 627 mm (24.7 in) DU penetrator with a 27 mm (1.1 in) rod diameter, [2] which reaches a muzzle velocity of 1,670 meters per second (5,500 ft/s) using 8.1 kg (18 lb) of JA-2 propellant. Its maximum effective ...
Standard 7.92×57mm Mauser armor-piercing K bullet introduced in mid-1917. Note the tool-steel core protruding from the rear of the bullet to form a boat tail. A tracer variation of the K bullet. The K bullet (from German 'Kern', core) was a 7.92×57mm Mauser armor-piercing bullet with a tool steel core designed to be fired from a standard ...
