Fe Vanadium 80 Grade Lumps Low Impurity Black Silver Colour Applied In Aerospace Steel Making

Fe Vanadium 80 grade lumps are a highly refined ferroalloy designed specifically for demanding sectors such as aerospace steelmaking, where stringent purity and performance criteria must be met. With a vanadium content around 80%, these lumps display a distinctive black-silver appearance caused by the presence of minor surface oxides combined with the metallic luster of vanadium-rich iron.

What sets this grade apart is its exceptionally low impurity level — sulfur and phosphorus typically remain below 0.03% — ensuring cleaner melts and reducing the risk of inclusions that could compromise mechanical integrity. In aerospace applications, steels must endure extreme stresses, temperature fluctuations, and corrosive environments.

The controlled addition of FeV80 aids in refining the grain structure, raising both tensile strength and fracture toughness. Vanadium forms stable carbides and nitrides during solidification, which act as pinning points to prevent grain coarsening, especially during reheating processes common in aerospace part fabrication.

Moreover, because of its low impurity profile, this ferroalloy helps maintain consistent weldability and fatigue resistance — essential qualities for landing gear, turbine shafts, and airframe components. The black‑silver coloration not only indicates the alloy's composition but also serves as a visual marker of proper handling and limited atmospheric exposure. Rapid dissolution characteristics enable efficient incorporation into electric arc or vacuum induction furnaces, shortening alloying cycles and improving production throughput.

Thanks to its combination of high vanadium concentration and ultra‑low impurities, FeV80 lumps provide a dependable route to producing ultra‑reliable aerospace steels capable of meeting rigorous certification standards.
