Experimental study on fatigue performance of high strength

Oct 01, 2018 · Costa et al. tested the fatigue performance of the welded joint of high-strength steels with 460-690 MPa yield strength and proved that the welded joint of high strength steels exhibited better fatigue performance than common steel materials. The fatigue strength of high-strength steels was higher than the estimated value of EN1993-1-9. FATIGUE PERFORMANCE COMPARISON AND LIFE fatigue strength at 106 cycles for forged steel was determined to be 359 MPa (52.1 ksi) and for the cast iron to be 263 MPa (38.1 ksi). Therefore the fatigue strength at 106 cycles was 37% higher for forged steel than the cast iron. This results in a factor of 30 longer life for the forged steel than the cast iron in the high cycle region.
