50CrVA has good mechanical and technological properties and high hardenability. Adding vanadium can refine the grain of steel, reduce overheating sensitivity, improve strength and toughness, and have high fatigue strength and yield ratio. However, due to cold deformation, it has poor weldability and low plasticity. It is an advanced spring, which is used as an important spring with large cross section and high load. Its working temperature is
The chemical composition of 50CrVA is as follows:
50CrV4 belongs to German standard spring steel, and the implementation standard is DIN 1722 1-88.
