SUP10 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 has a high yield ratio, but has poor weldability and low cold deformation plasticity. SUP10 is a relatively advanced spring steel used as a high load important spring with a large cross-section, as well as a valve spring, piston spring, and safety valve spring with a working temperature of<300 ℃.
