Abstract
The possibility is considered of using calculation methods to predict the risk of formation of the s-phase in the HAZ metal of chrome-nickel steels at a carbon content of about 0.08 % and higher. It is shown that the use of temperature-time constitutional diagrams for steel of a corresponding composition, combined with temperature cycles at points in the HAZ metal, allows predicting the degree of sensitization of the corresponding HAZ region under different welding conditions.
