Of late, the complexity of predicting fatigue life of engineering components is increasing exponentially due to the varied and multi-facet loading conditions, complex geometries, and newer materials coming up in the market. The current research includes the quantitative measurement of the influence of Annealing on the fatigue life of SAE 202 and 440C steels. Looking at the results, it was clearly evident that there is a definite improvement in the fatigue life due to Annealing in both the steels. However the extent of improvement in fatigue life was more in 440C steel when compared to SAE 202.
