ABSTRACT Bulletproof steel sheets are used for civilian applications like armouring cash money transfer vehicles and bank front points. The present work is dealing with controlled hot-flat rolling and post heat treatment cycle to develop rolled homogeneous bulletproof steel sheets for civilian applications. The steel alloy contains 0.3% C beside 0.93% Cr, 1.76% Ni and 0.62% Mo. The steel is additionally micro-alloyed with 0.004% B. 80 mm thickness steel slabs were controlled forged and followed by hot-flat rolling into 3 mm thickness sheets. A post heat treatment cycle was carried out for creation of bainite beside the martensitic structure to secure ballistic perforation resistance. Strips treated for 10 min. holding in a salt bath at 400 °C followed by water quenching contain 44% bainite and 56% martensite, possessing 388 HB, and present 1647 MPa σu and 1610 MPa σy. In addition to bainite and martensite phases, the microstructure contains ε-carbides measuring 600–800 nm. The ɛ-carbides were found embedded in the bainite aggregates and between the martensite laths. The sheets treated for 5 min. holding in the salt bath followed by water quenching showed up the highest value of σy indicating the highest resistance perforation among the others.
