50CrVA Spring Steel



Material Name


Material Name: 50CrVA

Characteristics and scope of application


50CrVA has good mechanical properties and process performance, high toughness, the addition of vanadium to make the steel grain refinement, reduce the thermal sensitivity, improve the strength and toughness, with high fatigue strength, yield ratio is also higher.
