50CrV4 is a German standard spring steel, equivalent to Chinese GB 50CrVA. 50CrV4 spring steel has good mechanical properties and process performance, high hardenability, adding vanadium to refine the grain of the steel, reduce overheating sensitivity, improve strength and toughness, have high fatigue strength, and have a high yield ratio. , But poor weldability and low cold deformation plasticity. It is a higher-grade spring, used as a high-load important spring with a larger section and a valve spring, piston spring, safety valve spring, etc. with an operating temperature of <300 &#;.
