9260 steel is a high-silicon spring alloy known for its excellent flexibility and resilience. These characteristics make this grade ideal for high-stress applications like the heavy-duty springs commonly found in automotive and railway suspensions. Its high silicon content not only enhances the steel’s strength and hardness but also improves its shock resistance and fatigue life.
