50CrVA spring steel

50CrVA spring steel

50CrVA spring steel, also referred to as 50CrVA spring steel, is an alloy of chromium, vanadium and steel. Its strength and hardness are very high, and its good plasticity and toughness meet the mechanical characteristics that are often required in spring steel. It has high fatigue strength, but its weldability, cold heading and cold extrusion performance are not very good.

50CrVA spring steel has the following features:

1, high strength: 50CrVA spring steel has high strength and high reliability, and its strength is higher than that of traditional carbon steel wire rods.

2, good plasticity and toughness: the comprehensive performance of 50CrVA spring steel is far superior to conventional spring steel, and its good plasticity and toughness are more suitable for the processing and forming of various springs.

3, high fatigue strength: 50CrVA spring steel, its fatigue strength is higher than 65Mn spring steel, and its fatigue strength, fatigue limit, tensile strength, compressive strength and other mechanical properties are in a relatively balanced range, and the fatigue performance is superior.

4, good machinability: the hardness and cutting performance of 50CrVA spring steel is lower than that of 65Mn spring steel, and its machinability is better, so it is convenient to process, manufacture and use.

Application of 50CrVA spring steel

50CrVA spring steel is widely used in the production of various types of springs, such as auto suspension springs, railroad springs, safety helmet springs, clutch springs, gasoline engine springs, torsion bar springs, steel wire tension springs, etc. It can also be used for the manufacture of heavy-duty pliers and cutting tools, as well as cold-drawn bolts, sleeves and other components.

Conclusion

In conclusion, 50CrVA spring steel is a kind of high-strength, high-reliability, good-plasticity and good-toughness steel. It has good fatigue performance and machinability, and it is the first choice for manufacturing spring components.

50CrVA alloy spring steel is a kind of high-end spring steel. The main steel grades and their corresponding chemical compositions are as follows:

C: 0.48-0.56

Si: 0.17-0.37

Mn: 0.50-0.80

Cr: 0.80-1.10

Ni: ≤ 0.30

Mo: ≤ 0.25

V: 0.15-0.25

50CrVa alloy spring steel has excellent comprehensive performance. Its mechanical properties are: tensile strength 1080-1280MPa, yield strength 1080-1280MPa, elongation 8-11%. It has good heat treatment property and strength after heat treatment. It is not easy to produce fatigue accidents and has abundant output.

50CrVA alloy spring steel is widely used in all kinds of high load weight spring, torsion spring, die spring, valve spring, engine valve spring and so on. It is also applied in the load weight spring of automobile engine, suspension and other important parts. 50CrVA alloy spring steel has good handling performance and it can be freely processed with machining, forging, cutting and heat treatment.

In summary, 50CrVA alloy spring steel has many advantages, such as good comprehensive performance, good heat treatment property and strength after heat treatment, abundant output, wide application and good handling performance. Therefore, it is a kind of preferred materials in the spring industry.
