The influence of additional heat hardening with the use of fast heating during austenitization on the armour resistance of high-strength sheet metal of protective purpose, made of medium-alloyed steel, is investigated. As established, the high-speed heat treatment by hardening and low tempering of slabs from rolled sheet with a thickness of 6 mm increases its ductility with unchanging the 4th class of leaves armour resistance. In addition to the possible inheritance of the deformation substructure, the increase in ductility after high-speed heat treatment while maintaining strength is due to significant grinding of the grain structure of steel.

Key words: high-strength steel, rolled sheet, high-speed heat hardening, austenitization, plasticity, ballistic tests, armour resistance.
