BULLETPROOF HETEROGENEOUS ARMOR OF ALLOYED STEEL FOR MEANS OF PERSONAL PROTECTION AND METHOD OF ITS PRODUCTION

FIELD: production of armor materials mainly used for means of personal protection. SUBSTANCE: bulletproof heterogeneous steel armor uses the face and back layers, whose Rockwell hardness is 62-67 and 46-51, respectively.

Heating for hardening is accomplished at a rate of 1.5 to 2.5 C/s up to a temperature of 920 to 950 C, seasoning at this temperature for 1 to 5 min, cooling in quenching medium. Low-temperaturetempering is accomplished at a temperature of 110 to 150 C. To produce armor. use is made of low-carbon steel containing, mas.%: carbon, 0.20-0.27; manganese, 0.30-0.90; silicon, 1.20-1.50; chromium, 1.0-1.50; nickel, 0.50-1.20; molybdenum, 0.15-0.35;iron, the balance.
