Ferrovanadium FeV80 (V 78–82%)

Ferrovanadium FeV80 is the high-vanadium master alloy steelmakers specify when every kilogram of vanadium has to land in the steel rather than in the slag. Supplied at 78–82% vanadium with tightly controlled carbon, phosphorus and sulfur, FeV80 from ZhenAn comes with a batch Certificate of Analysis (COA) for every heat - so your melt shop can verify chemistry before the material touches the furnace.

FeV80 is an iron–vanadium master alloy containing approximately 78–82% vanadium, balance iron. It is produced by aluminothermic or silicothermic reduction of vanadium pentoxide, then crushed and screened to the lump size your furnace charging system requires. Because it concentrates vanadium in a dense, metallic form, FeV80 additions dissolve quickly in the ladle and give the highest vanadium yield per ton of additive - the reason it is the default microalloying addition for high-strength grades. Where chemistry targets are less demanding, Ferrovanadium FeV60 and other lower grades offer a lower cost-in-use.

Typical values per GB/T 4139 / ASTM A102 practice - every shipment ships with a batch COA; confirm final limits against the COA before release. The full grade-by-grade table is in our ferrovanadium chemical composition chart.

Available lump sizes: 10–50 mm (other fractions on request). Packing: 1 MT ton bag or 100 kg steel drum.

The three grades do the same metallurgical job - putting vanadium into steel - but they differ in vanadium density, residual windows and cost-in-use. This comparison shows where each one pays off.

Rule of thumb: step up to FeV80 when vanadium targets rise or ladle weight budgets tighten; stay on FeV40/FeV60 where dilution is acceptable.

FeV80 is the workhorse addition for steels where small vanadium additions deliver large strength gains: HSLA structural plate and sections, high-strength rebar (HRB400/HRB500 class), tool and spring steels, and pipeline grades. Vanadium forms fine vanadium carbonitride precipitates during hot rolling, raising yield strength through precipitation strengthening while carbon stays low enough to preserve weldability. Many rebar mills pair it with vanadium nitrogen alloy to reach target strength with efficient vanadium use. Typical addition rates are a few tenths of a kilogram per ton of steel - your target chemistry and rolling schedule set the exact dosage.

Every FeV80 lot is sampled and analyzed in our in-house lab before packing, with third-party inspection (SGS / BV / CIQ) available on request. The COA accompanying each shipment reports actual V, C, Si, P, S and Al values against the ordered specification, so incoming inspection at your works is a verification, not an investigation.

ZhenAn is an ISO 9001 certified ferrovanadium manufacturer with two production bases and export experience to 100+ countries. We hold a free 1 kg sample and batch COA policy so new customers can qualify the material in their own lab before committing to a full lot.
