Ferro Vanadium FeV 75 High Purity Lumps
Ferrovanadium FeV 75, a high-purity FeV alloy with approximately 75% vanadium content, is a cornerstone additive in modern steelmaking, prized for its dual role as a deoxidizer and alloying agent. Characterized by its lustrous metallic silver hue, this Iron Vanadium Alloy delivers exceptional metallurgical performance, thanks to its ultra-low impurity levels and balanced composition.
Core Metallurgical Functions
Deoxidation: Purifying Molten Steel
Vanadium's strong affinity for oxygen makes FeV 75 a highly effective deoxidizer. During steelmaking, it reacts with dissolved oxygen in the molten bath, forming vanadium pentoxide (V₂O₅) that floats to the surface as slag, removing oxygen and preventing defects like porosity, blowholes, and inclusions.
Alloying: Enhancing Steel Properties
- Carbide Strengthening: Vanadium reacts with carbon to form fine, thermally stable vanadium carbides (VC), increasing hardness by 15-25% and wear resistance
- Grain Refinement: Vanadium inhibits grain growth during heating, resulting in finer microstructure and improved toughness
- Hardenability: Extends hardenability curve, allowing thicker sections to achieve uniform hardness after quenching
High Purity Specifications
FeV 75's "high purity" designation refers to its ultra-low impurity levels, achieved through advanced refining processes:
- Sulfur (S) ≤ 0.03%: Prevents hot shortness during hot rolling
- Phosphorus (P) ≤ 0.02%: Reduces brittleness in cold-formed steels
- Silicon (Si) ≤ 1.0%: Avoids excessive ferrite formation

Frequently Asked Questions
What is ferrovanadium?
Ferrovanadium is an iron–vanadium alloy used as a master alloy to introduce vanadium into steel and cast iron for strengthening and toughening.
Ferrovanadium definition and primary function?
It is an alloy of iron and vanadium, primarily used to add controlled amounts of vanadium to alloys, improving strength, wear resistance, and hardenability.
Difference between ferrovanadium and vanadium metal?
Ferrovanadium is an Fe–V alloy (typically 40–80% V) for adding vanadium to other metals; vanadium metal is nearly pure V, used in superalloys and chemicals.
