The paper describes the gage system designed for the various properties materials study. Within the study frameworks, the sections of pipes made of a new material — high-strength steel 08G2B of K65 steel grade were studied. These materials are ultra-low-carbon steels, wherefore it is possible to study their properties using the eddy current method. A subminiature eddy current transducer consisting of three windings on a core made of 81NMA alloy was used during the study. The resulting parameter of the gage system, which contains information on the object under study, was the change in the eddy current transducer signal. In this study, the samples with continuity defect models — cracks and holes — were investigated, and a study was conducted to simulate the corrosion presence in the metal.
