Description	The present work deals with the investigation of fretting influence on fatigue properties of steel parts with different strength. Steels EA1N and heat treated EA4T were used for the tests of fretting fatigue at fluctuating tension stress with low values of sliding. It was found that in the case of fatigue tests without fretting higher fatigue limit corresponded with the higher strength while the specimens subjected to fretting fatigue showed the fatigue limit values not too different from each other. The unfavorable effect of fretting on the fatigue properties is more pronounced in steels with higher strength . In the case of fretting fatigue, microstructural and fractographic examination and microhardness measurements revealed the important changes in the contact areas during the repeated cyclic process. These microstructural changes in thin surface layer eliminate substantially the original differences in strength values and can explain the suppression of the strength influence on the fatigue limit under the condition of fretting.
