    The article presents the results of research aimed at assessing the quality of forgings depending on the forging parameters used. The forging and subsequent heat treatment processes revealed the occurrence of cracks in the forgings. The article examines the possible causes of cracks, which can be caused by carburizing annealing and loss of plasticity during stress relaxation. Tool wear and damage during forging also affect the formation of cracks. These factors were identified as key factors contributing to the formation of non-metallic oxide inclusions, the transfer of surface defects and the formation of lamellar propagation during subsequent heat treatment. The findings highlight the influence of tool conditions and process parameters on the quality and reliability of steel forgings..
