This study investigates the effects of thickness, hardness and composition of modified layer on the plain and fretting fatigue properties of the nitrided 316 L steel plasma nitrided under various processing conditions. Fretting fatigue behaviour of untreated and nitrided material is also analysed with the finite element method. Experimental and theoretical fatigue life results are compared. The result indicates that the nitriding process improved the fretting fatigue properties of 316 L stainless steel. The experimental test results are close to theoretical fretting fatigue life results, thus it yields that the established model in the numerical analysis is consistent in this regard. ► We examined fatigue properties of nitrided 316 L steel as experimental and theoric. ► Plasma nitriding process improved plain and fretting fatigue life of 316 L steel. ► Theoretical fretting fatigue life results were compared with experimental results. ► Theoretical fretting fatigue life results were close to experimental results. ► Our theoretical approach was effective to determine fretting fatigue life.
