Heat Treatment Guide & Properties
50CrV4 is typically supplied in the annealed or quenched and tempered condition. Proper heat treatment is critical to achieve the desired spring properties, including high fatigue resistance and elastic limit.
Annealing
Improves machinability before final heat treatment.
Quenching
Oil quench to achieve high hardness.
Tempering
Balances strength, elasticity, and toughness.
Standard Lengths

■ Chemical Composition
The strength and fatigue resistance of 50CrV4 come from its balanced alloying. Chromium enhances hardenability and wear resistance, while Vanadium refines grain structure and improves fatigue strength. This composition allows the steel to perform reliably under repeated loading and shock conditions.
■ Mechanical Properties
After quenching and tempering, 50CrV4 delivers high tensile strength with excellent elastic recovery. It maintains good toughness even at high hardness levels, making it ideal for components subjected to cyclic stresses such as suspension and industrial springs.
