Niobium for advanced steel springs

Learn more:
• Trend towards the use of lower Carbon (to increase corrosion fatigue life) and Niobium
for grain refinement in order to keep the desired strength
• Niobium reduces hydrogen embrittlement tendency found in extra high strength spring
steels
• Vanadium and Niobium microalloying improves performance over traditional spring
steels
• Thermomechanical process in spring manufacturing ensures the optimization of
microalloying strategies
