Ferrovanadium lumps are iron-vanadium master alloys used to introduce vanadium into steel. Commercial grades vary mainly by vanadium content and impurity limits, with common ranges including FeV40, FeV50, FeV60 and FeV80. The correct grade depends on the required V addition, final steel chemistry and limits for elements such as C, Si, P and Al.
This guide explains the main ferrovanadium lump grades, their composition differences, common steelmaking uses, particle-size options and purchasing points.
Quick Answer
Ferrovanadium lumps are supplied in several vanadium grades rather than one fixed composition. FeV40 contains a lower V concentration, while FeV80 provides a much more concentrated vanadium addition. Higher-V grades require less total alloy mass for the same target V input, but the final selection should also consider C, Si, P, S and Al limits.
For steelmaking, ferrovanadium is commonly used where vanadium is added to support strength, grain refinement and alloy design in structural, spring, tool and other alloy steels.
What Are Ferrovanadium Lumps?
Ferrovanadium is an Fe-V alloy used as a vanadium-bearing addition material in steelmaking.
The term ferrovanadium lumps refers to the physical form of the alloy. Lump size is separate from chemical grade, so FeV40, FeV50, FeV60 and FeV80 can be supplied in different particle-size ranges according to the purchasing specification.
The grade name generally reflects the vanadium concentration range rather than one exact vanadium percentage.

Typical Ferrovanadium Grade Composition
The following table shows the ferrovanadium grades currently listed in our product range.
| Grade | V (%) | Al Max (%) | P Max (%) | Si Max (%) | C Max (%) |
|---|---|---|---|---|---|
| FeV40-A | 38–45 | 1.5 | 0.09 | 2.00 | 0.60 |
| FeV40-B | 38–45 | 2.0 | 0.15 | 3.00 | 0.80 |
| FeV50-A | 48–55 | 1.5 | 0.07 | 2.00 | 0.40 |
| FeV50-B | 48–55 | 2.0 | 0.10 | 2.50 | 0.60 |
| FeV60-A | 58–65 | 1.5 | 0.06 | 2.00 | 0.40 |
| FeV60-B | 58–65 | 2.0 | 0.10 | 2.50 | 0.60 |
| FeV80-A | 78–82 | 1.5 | 0.05 | 1.50 | 0.15 |
| FeV80-B | 78–82 | 2.0 | 0.06 | 1.50 | 0.20 |
The grade range should always be checked together with the complete impurity limits. A higher V percentage does not by itself define the suitability of the alloy for a specific steel grade.
What Do FeV40, FeV50, FeV60 and FeV80 Mean?
The grade number indicates the approximate vanadium level of the ferrovanadium alloy.
For example:
- FeV40: 38–45% V in the specification above
- FeV50: 48–55% V
- FeV60: 58–65% V
- FeV80: 78–82% V
This is why it is inaccurate to say that ferrovanadium always contains more than 50% vanadium.
If you want to understand how the grade number affects alloy addition, read what the grade number in ferrovanadium means.
What Are Ferrovanadium Lumps Used For?
Ferrovanadium is used mainly as a vanadium addition material in steelmaking.
The required grade depends on how much vanadium must be added and how much accompanying C, Si, P, Al and other elements the steel specification can tolerate.
High-Strength and Low-Alloy Steel
Vanadium is used in many high-strength and low-alloy steels as part of the alloy design.
The required FeV grade depends on the target V addition and the steelmaker's impurity limits. FeV80 can be useful where a more concentrated vanadium input is preferred, while lower-V grades may remain practical where a larger alloy addition is acceptable.
Structural Steel
Ferrovanadium can be used in structural steel grades where vanadium forms part of the required microalloying chemistry.
The final selection should be based on the steel specification rather than a general assumption that FeV80 is required for all structural steels.
Spring and Alloy Steel
Vanadium may also be used in spring and alloy steels where the required composition and heat-treatment route use V as one of the alloying elements.
Here again, the alloy grade should be selected from V demand and impurity tolerance rather than from steel category alone.
Tool and Specialty Steels
Higher-alloy and specialty steels may use ferrovanadium where controlled vanadium additions are required.
For tighter chemistry, the maximum C, Si, P and other impurity values become especially important.
How Does Ferrovanadium Grade Affect Alloy Addition?
A higher-V ferrovanadium grade provides more vanadium per unit mass.
The simplified theoretical calculation is:
Ferrovanadium Addition = Required Vanadium ÷ Vanadium Fraction
For example, using 40% and 80% V only as a simple comparison:
| Required V | FeV40 at 40% V | FeV80 at 80% V |
|---|---|---|
| 10 kg V | 25 kg alloy | 12.5 kg alloy |
| 50 kg V | 125 kg alloy | 62.5 kg alloy |
| 100 kg V | 250 kg alloy | 125 kg alloy |
This shows why FeV80 can reduce total alloy addition mass for the same theoretical V input.
The actual addition should use the real batch V content and plant-specific vanadium recovery rather than assuming exactly 40% or 80% V.
When Is FeV80 Preferred?
FeV80 is useful when a more concentrated vanadium addition is required.
Compared with lower-V grades, it allows the steelmaker to introduce the same theoretical V mass with less total ferrovanadium.
It may also be preferred where the FeV80 impurity limits better match the steel specification.
If your specification requires a high-V grade, see our Ferro Vanadium 80 product page.
When Is a Lower-V Ferrovanadium Grade Suitable?
FeV40, FeV50 or FeV60 may remain suitable when the process can accommodate the larger alloy addition and the grade meets the required impurity limits.
A lower V concentration does not automatically mean lower product quality. The correct grade depends on:
- required vanadium input,
- final steel chemistry,
- C, Si, P and Al limits,
- plant alloying practice,
- and total alloy cost.
Ferrovanadium Lump Size Options
Chemical grade and particle size are separate purchasing parameters.
Ferrovanadium lumps can be supplied in different size ranges according to the steelmaking and handling requirement.
Current supply options include:
- 10–50 mm
- 10–100 mm
The required size should be confirmed before ordering because lump size can affect handling, weighing and charging practice.
Do not assume that FeV80 must use a different particle size from FeV40. Grade and size should be specified separately.
Packaging and Delivery Options
Ferrovanadium lumps can be packed according to order size and handling requirements.
Available packing options include:
- 100 kg steel drums
- 250 kg drums
- 1,000 kg jumbo bags
The final packing format should be confirmed with the required grade, particle size and shipment quantity.
What Should Buyers Confirm Before Ordering?
| Parameter | What to Confirm |
|---|---|
| FeV Grade | FeV40, FeV50, FeV60, FeV80 or required chemistry |
| V Range | Required vanadium content |
| C / Si / P / Al | Maximum impurity limits required by the steel grade |
| Particle Size | 10–50 mm, 10–100 mm or agreed size |
| Packing | Drum or jumbo-bag requirement |
| COA | Actual batch chemical analysis |
| Quantity | Required shipment quantity |
| Application | Target steel grade or vanadium-alloying requirement |
A batch COA is more useful than relying only on the nominal FeV grade because it confirms the actual delivered chemistry.
Key Takeaways

- Higher-V grades provide more vanadium per unit mass and require less total alloy for the same target V input.
- C, Si, P, Al and other impurity limits should be checked together with V content.
- Chemical grade and lump size are separate specifications.
- The best FeV grade depends on the target steel chemistry, alloy addition requirement and actual COA.
FAQ About Ferrovanadium Lumps
What is the difference between FeV40 and FeV80?
FeV40 contains a lower vanadium concentration than FeV80. In the specifications shown here, FeV40 contains 38–45% V while FeV80 contains 78–82% V. FeV80 therefore requires less alloy mass to supply the same theoretical amount of vanadium.
Is FeV80 always better than FeV40?
No. FeV80 provides a more concentrated vanadium input, but the correct grade depends on the target V addition, impurity limits, steel chemistry and cost. A lower-V grade can still be suitable when it meets the process requirement.
What sizes are ferrovanadium lumps available in?
Current lump-size options include 10–50 mm and 10–100 mm. The required size should be confirmed separately from the ferrovanadium chemical grade.
What information should I provide when ordering ferrovanadium?
Provide the required FeV grade or V range, impurity limits, lump size, packing, quantity and target steel application. If you already have a purchasing specification or previous COA, send it for direct comparison.
Need to Confirm a Ferrovanadium Grade?
If you already have a ferrovanadium purchasing specification, send the required V range, C/Si/P/Al limits, lump size and quantity. We can compare available grades on the same chemistry basis rather than selecting only from the FeV grade name.
