Corrosion and Temperature have a significant deteriorative effect on fatigue life of mechanical structures. The reliability of the fatigue damage assessment techniques depends on the quality of the S-N curve which is derived as a result of corrosion degradation and elevated temperature. In this research paper steel specimens of 9.48 mm diameter were tested under rotating bending conditions at a frequency of 6000 cpm.The influencing factors are stress concentration (K = 2.45) (common for both the cases) corrosion (1 percent NaCl solution as corrodent) and elevated temperature (150 °C). The S-N curve so obtained were compared with experimental fatigue test results. Their correlation showed good agreement between the experimental results and the adopted approaches for fatigue life assessment.
