Abstract
The paper considers an experimental method for assessing the degradation of physical and mechanical properties of steel elements subjected to accelerated corrosion.
The study is based on tests of St3ps steel specimens with three samples by types of profile sections (round, rectangular, angle) The methodology includes two stages: electrochemical corrosion in 5% NaCl solution with fixation of mass loss and wall thickness of samples, as well as mechanical tensile tests of reference strips obtained in accordance with GOST 7564-73. To check the change of physical and mechanical properties of the metal from the action of corrosion and specifically its embrittlement, the dependence of corrosion resistance of steel elements on the shape of their cross-section and geometric parameters was experimentally tested.
