Metallic Grey Alloy for Cast Steel Nodularization and Grain Refinement

Product Overview

Industrial ferrovanadium FeV 78, supplied as metallic grey granules, is a specialized FeV alloy engineered to optimize cast steel properties through nodularization and grain refinement. With approximately 78% vanadium content, it bridges the gap between mid-range grades (e.g., FeV50) and ultra-high-purity variants (e.g., FeV80), offering a balanced combination of performance and cost for demanding foundry applications.

Core Functions in Cast Steel Processing

Cast steel, used in components like gears, valves, and mining equipment, requires uniform microstructure and high mechanical strength. FeV 78 granules address two critical needs:

Nodularization: Promoting Spherical Graphite Formation

In ductile cast iron (a subset of cast steel), graphite shape dictates properties—flaky graphite causes brittleness, while spherical graphite (nodular) enhances toughness. FeV 78 acts as a nodularizer by:

Providing vanadium, which reacts with sulfur and oxygen in the melt to form stable compounds (e.g., VS, VO), reducing interfacial tension between graphite and the liquid metal
Encouraging graphite to nucleate as spheres rather than flakes, resulting in a matrix reinforced by uniformly distributed nodules

This transformation improves ductility, impact resistance, and fatigue life—essential for cast steel parts subjected to dynamic loads.

Grain Refinement: Controlling Austenite Growth

During solidification, cast steel tends to form coarse austenite grains, which weaken mechanical properties. FeV 78's vanadium atoms segregate to grain boundaries, pinning them and inhibiting growth. The result is a finer ferrite-pearlite or bainitic microstructure, which:

Increases yield strength and hardness
Enhances toughness and resistance to crack propagation

Advantages of the 78% Vanadium Grade

Balanced Potency: FeV 78 delivers stronger nodularizing and grain-refining effects than FeV50 (50% V) but at a lower cost than FeV80 (80% V)
Granule Form: The granular morphology (typically 1–5 mm) ensures rapid dissolution in the ladle, uniform distribution, and minimal dust generation
Low Impurities: Strict control over sulfur (<0.05%) and phosphorus (<0.04%) prevents harmful inclusions

Conclusion

Ferrovanadium's ability to impart excellent thermal stability makes it indispensable in heat-treatable alloy production. By forming stable carbides, refining grains, and strengthening the matrix, it enables steels to withstand extreme conditions while maintaining the mechanical properties required for modern engineering applications. As demand grows for lighter, stronger, and more durable materials, ferrovanadium will remain a key enabler of innovation in the steel industry.
