Ferro Vanadium (FeV) is a master alloy that delivers vanadium to liquid steel for micro-alloying. Even at low addition, vanadium forms fine V(C,N) carbonitrides that precipitate during cooling and pin austenite grain boundaries, refining grain size while raising yield strength, toughness and wear resistance without a separate heat treatment. This grade carries V at 78-82% with C held to 0.30% max, P 0.06% max and S 0.05% max, suiting clean-steel chemistries where residuals must stay tight. Si is capped at 2.0% and Al at 1.5%, with 10-50mm sizing for controlled dissolution and stable recovery in ladle or EAF practice. Typical additions run 0.05-0.20 wt% V depending on target strength, common across HSLA structural plate, micro-alloyed rebar, spring steels and tool steels; FeV is also a feedstock for long-duration vanadium-flow energy storage. Every lot ships with COA and MTC. Multi-regional sourcing covers CIF Marmara delivery in 20 MT FCL or 5 MT LCL lots. Send your grade, tonnage and delivery terms for a current RFQ.

Häufig gestellte Fragen
Which FeV grade and spec should I specify for HSLA and rebar micro-alloying?
For HSLA, rebar, spring and tool steels the standard choice is FeV80, supplied here at V 78-82% with C ≤ 0.30%, Si ≤ 2.0%, Al ≤ 1.5%, P ≤ 0.06% and S ≤ 0.05%. The low carbon and residual limits suit ladle or furnace additions where you control final C and avoid embrittling residuals. Size is 10-50 mm lump. State your target V recovery and any tighter Al or N ceiling on the PO so we can confirm the lot meets it.
What addition rate gives a target vanadium content in the steel?
Vanadium micro-alloying typically targets 0.03-0.15% V in the finished steel, so additions are small. As a rule, each 1 kg of FeV80 per tonne of liquid steel adds roughly 0.08% V before recovery losses. Plan on about 75-90% V recovery for late ladle additions under good practice. Work backward from your target residual V and your own measured recovery; add for late, with stirring, to keep recovery high and the alloy dissolved.
How is FeV80 packed, and what are typical MOQ and lead time?
Standard packing is 10-50 mm lump in sealed steel drums or 1 MT big bags on pallets, palletized for FCL stacking. Typical order sizes run from 5 MT LCL up to full 20 MT FCL, with smaller drum quantities available against bonded stock. Lead time depends on lot availability and chosen Incoterm (for example CIF Marmara or ex-bonded Gebze). Send your tonnage, port and required delivery window and we will confirm the schedule against current multi-regional sourcing.
What quality documentation and testing come with each lot?
Each lot ships with a COA / MTC stating heat or lot number and the assayed V, Si, Al, C, P and S against the FeV80 spec. Chemistry is determined by standard methods (XRF and wet analysis for V; LECO for C and S). Size distribution is reported to the 10-50 mm range. If you require third-party sampling, a witnessed assay, or analysis to a specific ASTM or DIN method, note it on the PO before shipment so it is built into the inspection plan.
When can FeNbV, nitrided vanadium, or VN replace FeV80, and when should I not substitute?
For plain strengthening via fine V(C,N) precipitation, FeV80 is the direct, lowest-residual route. Nitrided ferrovanadium or VN alloy can lift yield strength further when you want a higher N:V ratio and finer precipitates, often at lower V addition. FeNb or FeNbV shifts the strategy toward Nb-based grain refinement with different recrystallization behavior. Do not swap across these without re-checking your steel's N level, finishing temperature and target mechanicals, since the precipitation chemistry and recovery differ.
