Purpose: In this paper was set the aim to determine energy breaking during the impact test. As part of the work, the strength of the bimetallic plates exposed to cracking as a result of dynamic bending forces from the two layers as well as across the connection area of bimetallic plate was analyzed. Design/methodology/approach: To determine the technological properties of this group of materials are specially intended standards but none of them do not determine how to test the impact energy of such group of materials. In this paper are presented results of such test, with macro and microscopic analysis of fracture and merging area. Findings: Based on the results of laboratory tests can be concluded that the most exposed, X6CrNiMoTi17-12-2 - PN355NH bimetallic material, to the dynamic breaking are samples arranged according to variant a3 (i.e.. across the height of the bimetal layers merging zone). Research limitations/implications: This work aimed to highlight the problem of the bimetallic material resistance to cracking according to different initialization direction. Originality/value: The study attempts to identify how the material must be placed in the finished product to reduce as far as possible its exposure to crack. An important element in the correct determination of the impact of the material according to PN-EN ISO 148-1:2010 is the appropriate cutting of notch. For this purpose, a single-pass cutter guarantying to obtain uniform parameters of fracture initiation was developed.
