The variation in the structure and properties of cast iron sealing rings (content in wt %: 2.8–3.0 Si; 0.4–0.6 Mn; 0.1–0.2 Cr; 0.5–0.6 Ni; 0.7–0.9 Cu; 0.04–0.06 Mg; 2.8–3.0 C) under their exposure to a 5.28 MHz pulsed magnetic field is studied. Variations in the eutectoid morphology, the internal structure of the graphite inclusions, and the size of the free cementite inclusions, which result in the enhancement of the hardness, are observed. The magnetic pulse treatment of rings induces compression stresses in them. The
physicomechanical properties of the rings change periodically upon the variation of the number of treatment cycles. The optimum mode corresponds to two cycles.
