The change in mechanical properties and structural state is studied for steel of strength class K65 after heating to different temperatures. The change in strength properties with heating in the temperature range for precipitation of fine particles of Nb and V carbides is compared with particle morphology. Recommendations are worked out on the basis of results obtained for improving the mechanical properties for high-strength steels with a ferrite-bainite structure.
