Protac 500 - A new genaration of armoured steel

The engineers of the biggest Slovenian steelwork ACRONI d.o.o. in cooperation with domestic and foreign institutions of science have been designed and developed a new genaration of armoured steel PROTAC 500. Steel PROTAC 500 belongs to the group of high strength low alloy (HSLA) steels. It is made in steelwork ACRONI d.o.o. by the standard industrial procedures. The relevant mechanical properties of that steel are achieved by quenching and tempering. Preliminary tests of the mechanical properties of the steel have indicated the possibility of using steel PROTAC 500 for light armoured vehicles. The presented work studied the response of new generation armored steel plates PROTAC 500 to the ballistic testing with armoured piercing bullets with a core of tungsten carbide, charge 7.62 mm. However, the interactions between the piercing bullets and the armoured steel plate were also investigated.
