Abstract
 This paper introduces a novel method for estimating the fatigue behavior of stainless steel 304 through a single tensile test. By utilizing the engineering and true stress-strain curves, the constants of the Basquin equation were derived. A significant innovation is the calculation of the true fracture stress, σ f, using the Bridgman correction from the tensile test. This σ f is equated to the Basquin constant σ'f, and the fatigue limit is approximated as half the ultimate tensile strength, allowing for the estimation of alternating stress, σa, for infinite cycles. The Basquin constant b was then adjusted based on calculated σa and σ'f values across various cycle counts. The estimated values for σ' f and b of 304 stainless steels are 1248.7 MPa and -0.07, respectively. The resulting fatigue curve showed good correlation with established data for stainless steel 304, presenting a cost-effective and efficient alternative to traditional fatigue testing, which is beneficial for engineers designing cyclically loaded components.
