Abstract
A comprehensive study of parts made of low-carbon steel grades DC04 and DX54D was carried out in order to establish the causes of the formation of surface cracks using optical and electron microscopy, chemical analysis and metallography, the structure was assessed, the chemical composition, the structure of surface cracks and artificially obtained fractures of parts were studied. An X-ray spectral microanalysis of the surface of the opened cracks was carried out. A decrease in ductility due to contamination of the parts material with non-metallic inclusions has been established.
