What is ferro vanadium FeV80 used for?
Leave a message
Ferrovanadium FeV80 (approximately 80% vanadium, balance iron) is primarily used as an alloying additive in steelmaking. Its function is to introduce vanadium into molten steel in a controlled and efficient manner.
Primary Uses of FeV80
High-Strength Low-Alloy (HSLA) Steels
Vanadium forms fine vanadium carbides and nitrides (VC, VN), which significantly increase strength and toughness through grain refinement and precipitation strengthening.
Common applications include structural steel, bridges, pipelines, and automotive components.
Tool and Alloy Steels
Improves hardness, wear resistance, and high-temperature stability.
Used in tool steels, spring steels, and bearing steels where fatigue resistance is critical.
Rebar and Construction Steel
Allows producers to achieve higher yield strength without increasing carbon content, improving weldability and ductility.
Widely used in seismic-grade reinforcement bars.
Heat-Resistant and Creep-Resistant Steels
Vanadium enhances resistance to creep and thermal fatigue, making FeV80 suitable for steels used in power plants, boilers, and pressure vessels.
Why FeV80 Specifically
High vanadium content (≈80%) means smaller addition volumes and more precise alloy control.
Good dissolution and recovery rate in molten steel.
Lower impurity levels compared with lower-grade ferrovanadium products.
Typical Vanadium Addition Levels
Generally 0.05–0.25% V in steel, depending on grade and performance requirements.
