The publication is part of a new trend in popularizing Industry 4.0. The primary objective is to present the key directions in the transformation of the steel industry from steelworks 3.0 to steelworks 4.0. The work was based on a literature review and data analysis on steel 4.0 technologies. The analytical part of the thesis was prepared on the basis of the Polish steel sector (sections from the classification of economic activities: 24 and 25). On the basis of the literature study, a thesis was formulated about the need to digitize processes in enterprises heading for Industry 4.0. The application of selected technologies (ICT) in the Polish steel sector (percentage of companies using the analyzed technologies in the total number of enterprises in the sector) constitutes the scope of the research. Further research will be carried out in the area of digitization development in steel Industry toward steel 4.0.
