Grades Of Ferro Vanadium

1. High-Grade Ferrovanadium (FeV80 & FeV75)

Vanadium Content: 75–85% (FeV80 typically contains 78–82% V, while FeV75 has 70–75% V).

Impurities: Low levels of carbon (<0.15%), sulfur (<0.05%), and phosphorus (<0.05%).

Applications: Used in high-performance alloys, aerospace steels, and tool steels where superior strength and heat resistance are critical.

2. Medium-Grade Ferrovanadium (FeV50 & FeV60)

Vanadium Content: 50–65%.

Impurities: Slightly higher carbon (<0.4%) and silicon (<2.0%) compared to high-grade FeV.

Applications: Common in construction steels, pipelines, and automotive components requiring balanced strength and weldability.

3. Low-Grade Ferrovanadium (FeV40 & Below)

Vanadium Content: 35–45%.

Impurities: Higher carbon (<0.6%) and silicon (<3.0%), but more cost-effective.

Applications: Used in reinforcing bars (rebar), general structural steels, and cast iron for moderate strengthening.

Specialty Grades (Nitrided FeV, FeV-Al Alloys)

Nitrided FeV: Contains vanadium nitride (VN) for microalloyed steels requiring grain refinement.

FeV-Al Alloys: Used in titanium alloys and specialty welding electrodes.

The choice of grade depends on cost, required vanadium content, and steelmaking process. High-grade FeV is preferred for critical applications, while low-grade FeV is economical for bulk steel production.
