PROJECTILE WITH BODY FROM HIGH-FRAGMENTATION SILICEOUS STEEL OF ODINTSOV-BOTVINA

摘要

FIELD: weapons and ammunition.;SUBSTANCE: projectile comprises body made of high-fragmentation siliceous steel by hot stamping with further heat processing, which comprises 0.7-0.9% of carbon and 2% of silicon, at that its relative narrowing during rupture makes at least 15%, and in process of blast testing of fragmentation cylinders RSFC No.12 made from it, equipped with TNT and composition A-IX-2, relative mass of average fraction of fragments 1m≤4 g makes accordingly at least 0.4 and 0.45, and number of fragments with mass of more than 0.25 g accordingly at least 1500 and 2000.;EFFECT: higher efficiency of body crushing into fragments.;2 dwg, 3 tbl
