Experimental Study on the Effect of Annealing on Fatigue Life of SS 304 Steels

Abstract

Fatigue failure is one of the main reasons for the mechanical failure in engineering materials. To improve the fatigue strength of the material one of the most used method is heat treatment of the materials in which hardness, wear resistance and aesthetics is improved. 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. In this paper the the quantitative measurement of the influence of Annealing on the fatigue life of SS 304 steels. Theresults conculed clearly clearly that there is a definite improvement in the fatigue life due to Annealing in steel. However the extent of improvement in fatigue life was more in SS 304 (after annealing) when compared to SS 304(before annealing).
