Data on interaction of phase, structural and magnetic properties of ferritic-pearlitic steel 12Kh1MF, both in the initial condition and after operation were obtained. It is shown that the highest intensity and magnitude of magnetic response variation are manifested in the metal of heating surface pipes, which have been in operation and have the structure different from the initial one. A possibility is presented of using the magnitude of jumplike changes of magnetic field intensity based on Barkhausen effect, in order to detect zones with inadmissible structural changes in the metal of the heating surfaces, as well as zones of maximum stress concentration, located in the risk zone. 8 Ref., 1 Tabl., 8 Fig.
