2. Fatigue resistance : The material is engineered to withstand millions of stress cycles without failure, making it very durable for parts in dynamic environments.
3. Hardenability: Its high hardenability ensures consistent strength across the entire spring, even in thicker sections, enabling it to handle heavy loads.
4. High-stress applications: It is suitable for large, important coil springs that operate under high stress and alternating loads.
