The fatigue-crack growth rate of Type 304 stainless steel was studied at 1000 F with cyclic frequencies ranging over approximately 4 1/2 orders of magnitude. It was found that as frequency decreased, the fatigue-crack growth rate showed a significant increase, and the behavior could be characterized by an equation of the form da/dN = A(f) [ΔK]n, where the exponent n represents a constant for all of the frequencies studies.
