50CrV4 Alloy Spring Steel Wire

↵

50CrV4 alloy spring steel wire is a high-strength spring wire made of chromium vanadium alloy steel as the base material and through quenching and tempering treatment. It is mainly used for springs and mechanical elastic elements that can withstand high cyclic stress and impact loads.

Suitable for high cyclic stress springs
Tensile strength 1100–1400 MPa, yield strength 800–1100 MPa. Quenching and tempering create a martensitic + tempered structure, ensuring the steel wire retains elasticity and reduces the risk of fatigue fracture during repeated tension or compression.

Available to various sizes
Diameter 0.5–12 mm, available in coils or fixed lengths, facilitating the manufacture of various types of springs and mechanical elastic components.

Good processing adaptability
Elongation 10–15%, ensuring minimal cracking during tension, winding, or cold bending. The bright, rust-free surface facilitates subsequent processing or direct assembly.

Automotive and Motorcycle Industry: Used in the manufacture of suspension springs, clutch springs, and brake springs, ensuring elasticity and lifespan under high cyclic load conditions.

Machinery Manufacturing Industry: Used in compression springs, tension springs, and vibration components for mechanical equipment, bearing repetitive and impact loads.

Construction Machinery and Heavy Equipment: Used in shock absorber springs, traction springs, and buffer components, adaptable to high load and vibration environments.

Aerospace and Transportation Equipment: Used in lightweight springs, control springs, and connecting elastic elements, maintaining structural function under high-frequency cyclic stress.
