50CrV4 Spring Steel



Material Name


Material Name: 50CrV4

Characteristics and scope of application


Good mechanical and technological properties, quenching high, adding vanadium steel grain refinement, reducing overheating sensitivity, improves the strength and toughness, has high fatigue strength, yield ratio is relatively high, but the welding of poor, cold due to plastic deformation is low. It is a kind of higher spring, used as a larger cross section of the high load important spring and working temperature < 300 DEG C valve spring, the piston spring, and a safety valve spring.
