Iron Vanadium Alloy 80 Percent Vanadium Dense Lumps
Iron Vanadium Alloy 80 percent vanadium dense lumps are a premium-grade FeV alloy (ferrovanadium) designed to elevate the performance of structural steel and pressure vessel plates — materials critical to infrastructure, energy, and industrial applications. With ~80% vanadium content, this Vanadium Iron Alloy (often labeled FeV80, Ferrovanadium 80, or FeVanadium 80) delivers unmatched carbide-forming potency and grain refinement, while its dense lump form (10–50 mm, metallic grey-silver) ensures efficient processing in large-scale steelmaking.
Core Metallurgical Advantages
Exceptional Strength Enhancement
Vanadium's strong affinity for carbon drives the formation of fine, thermally stable vanadium carbides (VC) during solidification and heat treatment. In structural steel, these VC particles (≤1 µm) act as micro-reinforcements, increasing yield strength by 20–30% and ultimate tensile strength (UTS) by 15–25% compared to non-alloyed counterparts.
Superior Toughness & Impact Resistance
Vanadium refines austenite grains during heating, resulting in a finer ferrite-pearlite or bainitic microstructure. This refinement enhances toughness, as smaller grains impede crack propagation—critical for structural steel in seismic zones or pressure vessels exposed to low-temperature environments.
Weldability & Defect Resistance
Ultra-low impurities (S ≤ 0.03%, P ≤ 0.02%) in FeV80 minimize the risk of weld defects like hot cracking and hydrogen-induced cold cracking (HICC). This ensures strong, reliable welds in structural steel frameworks and pressure vessel joints.
Dense Lumps: Form & Functional Benefits
- Rapid Dissolution: Dense particles melt quickly in molten steel, ensuring uniform vanadium distribution and reducing furnace processing time.
- Low Dust Generation: Minimal surface area compared to powder reduces airborne particles, improving workplace safety and material efficiency.
- Easy Handling: Lumps are compatible with automated dosing systems and stackable for bulk storage, streamlining operations in steel mills.
