50CrVD spring steel strip coil

50CrVD alloy spring steel, 50CrVD Good mechanical properties and process properties, high hardenability, adding vanadium to refine the grain of steel, reduce overheat sensitivity, improve strength and toughness, high fatigue strength, yield ratio Higher, but poor weldability and low cold deformation plasticity. It is a higher-grade spring used as a high-load important spring with a large cross section and a valve spring, piston spring, safety valve spring, etc. with an operating temperature <300 °C.
