Usage/Applications

Mechanical Properties are good. 50CrVA have high hardenability. The element V reduces thermal sensitivity and improves the strength and toughness. The fatigue strength and yield point are high but the weld ability is bad.

-50CrVA is a nice material of spring. Usually it’s used as valve spring, piston spring and secure valve spring with big section that can bear much load. The working temperature is below 300
