Influence of Technological and Operational Factors on Fatigue Resistance of 10GN2MFA Steel*

  • Published:
Strength of Materials Aims and scope

The paper presents the results of low-cycle fatigue tests for 10GN2MFA steel obtained by martensitic melting and electroslag remelting in air and in heat transfer medium at both room and elevated temperatures, as well as cyclic crack growth resistance in high-temperature aqueous medium. It is shown that the method of steelmaking exerts a strong influence on the fatigue crack growth stage.
