To reduce the weight of suspension coil springs for automobiles, high-strength steel has been developed. However, in general, strength and corrosion fatigue are contradictory. Therefore, the technology basis is to raise durability and sag resistance. Moreover, further improvement of the corrosion fatigue strength is important. As a solution for this problem, element design, which improved the performance against corrosion, and optimum condition of shot peening process were studied. As a result, high-strength suspension coil springs having superior corrosion fatigue strength compared with the spring made of SAE9260 were developed.
