Ferrovanadium 40 (FeV40) is a ferroalloy containing approximately 40% vanadium and balance iron. It is widely used in steelmaking as a cost-effective vanadium additive for improving strength, toughness, wear resistance, and grain refinement. Compared with higher-vanadium grades such as FeV50 or FeV80, Ferrovanadium 40 offers an economical solution for structural steel, rebar production, alloy steel manufacturing, and foundry applications.
As global steel producers continue to pursue higher-strength and lower-carbon steel solutions, Ferrovanadium 40 remains one of the most widely used vanadium alloys due to its balance of alloying efficiency and economic value.

maybe you want to know about Ferrovanadium 40
Q1. Why choose FeV40 instead of FeV50 or FeV80?
FeV40 offers an excellent balance between alloying efficiency and cost. For many structural steel, rebar, and general engineering applications, FeV40 provides sufficient vanadium content to achieve the required mechanical properties while reducing alloying costs compared to higher-grade ferrovanadium products.
Q2. What is the recovery rate of vanadium when using FeV40?
The recovery rate depends on steelmaking practices, furnace conditions, slag chemistry, and addition methods. Under properly controlled conditions, FeV40 provides stable vanadium recovery and efficient alloy utilization during steel production.
Q3. Can FeV40 be used in electric arc furnace (EAF) steelmaking?
Yes. FeV40 is widely used in electric arc furnaces (EAF), basic oxygen furnaces (BOF), and secondary refining processes. It can be added during various stages of steelmaking depending on the desired alloy composition.
Q4. What is the difference between ferrovanadium and vanadium nitrogen alloy?
Ferrovanadium primarily supplies vanadium as an alloying element, while vanadium nitrogen alloy provides both vanadium and nitrogen. The choice depends on steel grade requirements, alloy design, and production processes.
Q5. Does FeV40 improve fatigue resistance?
Yes. Vanadium helps refine the grain structure and promotes the formation of stable precipitates within the steel matrix. These metallurgical effects significantly improve fatigue resistance and long-term durability under cyclic loading conditions.
Q6. Is FeV40 suitable for high-strength low-alloy (HSLA) steel?
Absolutely. FeV40 is commonly used in HSLA steel production because it enhances strength, toughness, and weldability while requiring relatively low addition levels.
Q7. How does vanadium contribute to grain refinement?
Vanadium forms fine carbides and nitrides during steel processing. These particles inhibit grain growth, resulting in a finer and more uniform microstructure that improves both strength and toughness.
Q8. What Particle Sizes Are Available For Ferrovanadium 40?
Common sizes include:
10-50 mm
10-100 mm
Customized sizes upon request
Q9. How Should Ferrovanadium 40 Be Stored?
Store in a dry and ventilated environment to prevent moisture absorption and contamination.
Q10. Is Ferrovanadium 40 Suitable For Rebar Production?
Yes. FeV40 is widely used in high-strength reinforcing bar production to achieve improved yield strength and reduced alloying costs.
Q11. What International Standards Does Ferrovanadium 40 Comply With?
Production can be supplied according to:
GB/T standards
ASTM requirements
Customer-specific specifications
Q12. Can Customized Chemical Composition Be Provided?
Yes. Customized vanadium content, carbon limits, particle sizes, and packaging solutions are available according to customer requirements.
