In compression coil springs subjected to cyclic load, fatigue cracks can sometimes initiate and propagate from scratch-like small defects produced during the manufacturing process and degrade the fatigue strength. In this study, torsional and rotating bending fatigue tests were conducted to examine the fatigue behavior of a high-strength spring steel (JIS G 3561, SWOSC-V) in the presence of small scratches. The sensitivity of the HCF and VHCF strength to small scratches was evaluated based on the √area parameter model.
