The present work considers the effect of fabricating process on fatigue behavior of high strength low alloy steel (HSLA), which is used to be structural steel. HSLA steel has been designed to provide specific combinations of formability and weld ability properties for fabricating process. Rectangular bar specimens taken from different stages of fabricating processes were used to perform the four-point bending fatigue test under the stress ratio, R, of 0.1. Effects of forming and cold spinning on fatigue performance were investigated comparing with that of as-rolled plate. The results indicated that the increase in fatigue limit resulted from work hardening due to fabricating process.
