80 % ferrovanadium (FeV80) contains 78–82 % vanadium, with iron and minimal deoxidizers. It is a premium‑grade alloy used when maximum vanadium content per addition is required, minimizing the amount of ferroalloy needed and reducing impurity introduction.

1. Premium Tool Steels & High‑Speed Steels

   • Essential for manufacturing drill bits, end mills, dies, and cutting tools that require high hardness, hot hardness, and excellent wear resistance.

   • Vanadium forms very hard carbides (VC) that greatly improve edge retention.

2. Aerospace & Defense Alloys

   • Used in nickel‑base and titanium alloys for turbine blades, landing gear, and armor materials where high‑temperature strength and corrosion resistance are critical.

3. Specialty & Ultra‑High‑Strength Steels

   • Added to maraging steels and other advanced high‑strength steels for aerospace, military, and motorsport applications.

4. Battery & Chemical Industries (Indirect)

   • High‑purity vanadium from FeV80 can be extracted for vanadium redox flow batteries (VRFBs) and catalyst production, though this is a niche compared to steel use.

5. Small‑Addition Alloying

   • Because of its high V content, smaller quantities are needed to achieve target vanadium levels, reducing slag bulk and minimizing tramp element pickup.

• Maximum vanadium efficiency: Fewer kilograms per ton of steel needed to reach desired V content.

• Cleaner steel: Lower iron content means fewer impurities from the ferroalloy itself.

• High performance: Enables steels and alloys with superior wear resistance, hot hardness, and high‑temperature stability.
