What is Grade 75-80 Ferro Vanadium mostly used for?

Grade 75–80 Ferro Vanadium (typically 75–80% vanadium, balance iron) is mostly used as a vanadium alloying additive in carbon steel and low-alloy steel production. Its primary role is to improve mechanical performance while maintaining good manufacturability.

Main Applications

Reinforcing Bar (Rebar) Steel – Primary Use

The largest consumption of Grade 75–80 FeV is in construction rebar, especially high-strength grades (e.g., HRB400/500 or ASTM A615 Grade 60/75).

Vanadium significantly increases yield and tensile strength through grain refinement, allowing lower carbon levels and better weldability.

Structural and HSLA Steels

Used in high-strength low-alloy (HSLA) steels for buildings, bridges, and large steel structures.

Enhances strength, toughness, and fatigue resistance with minimal alloy addition (typically 0.05–0.15% V).

Automotive and Engineering Steels

Applied in medium-carbon steels for axles, crankshafts, fasteners, and forgings where strength-to-weight ratio is important.

Pipeline and Pressure-Bearing Steels

Improves grain refinement and toughness, supporting compliance with demanding mechanical property standards.

Why Grade 75–80 Is Preferred

Cost-effective compared with higher-purity grades (e.g., FeV80+), making it ideal for mass steel production.

High vanadium recovery in steelmaking with reliable dissolution.

Sufficient purity for most carbon and low-alloy steel grades, where ultra-low impurities are not critical.

Typical Addition Levels

Usually 0.03–0.20% vanadium in finished steel, depending on grade requirements.
