6150 has good mechanical and technological properties and high hardenability. The addition of vanadium refines the grain size of the steel, reduces overheating sensitivity, improves strength and toughness, has high fatigue strength and high yield ratio, but poor weldability and low cold deformation plasticity.6150 is a kind of higher spring, which is used as a high load important spring with large section and valve spring, piston spring and safety valve spring with working temperature<300 ℃
