Variability in published strain-cycle fatigue data was essentially independent of grade and strain amplitude for life <2×106 reversals. Correlations between tensile properties and strain-cycle fatigue parameters were either not statistically significant or so highly variable as to be of doubtful practical importance. However, for a life of 2×106 reversals, total strain amplitude Δɛ/2 bore a significant relation to tensile strength σu. Present findings emphasize the need for caution in estimating life when data are unavailable since such estimates encompassed a range in life 10 to 100 times greater than was actually observed.
