It is one of the newer generation of steels with ultra-high strength, high hardness, and good ductility. It is used in the dedicated industry to produce tank armours and other armoured vehicles. The characterization of the material also involves looking at its behaviour in the presence of a crack-type defect. In this work, tensile properties, impact toughness (Charpy), and K JIc were tested. The obtained results of fracture mechanic tests indicated good resistance against the crack type faults. © 2023 The Authors. Published by ELSEVIER B.V.

Introduction Steels for anti-ballistic protection are used for military purposes to produce armoured vehicles and objects that require anti-ballistic protection. Estimated, more than 800,000 tons per year of protective plates have been produced for military purposes such as armoured fighting vehicles [1]. For the safety and functionality of the armour, it is necessary to choose the appropriate material during development of the product [2]. PROTAC SA500 steel is a newer generation of steel, produced in the Slovenian steel mill Acroni Jesenice. To ensure the safety of armoured vehicles and buildings made of this steel, it is necessary to fulfil the expected operating conditions efficiently, economically, and safely. That is, during exploitation no damage resulting in loss of structure’s functionality may occur [3].
