FeVN is not a naturally occurring material - it is a manufactured ferroalloy produced by adding nitrogen to ferrovanadium during industrial processing. Therefore, its "abundance" is tied to:
Availability of raw materials:
Vanadium comes from minerals (vanadiferous magnetite, sandstone-hosted deposits, petroleum residues) and is mined mainly in China, Kazakhstan, South Africa, and the United States.
Nitrogen is obtained from the air (air separation) or as ammonia-derived nitrogen, which is plentiful.
Production capacity:
FeVN is produced in limited volume compared to plain ferrovanadium because its niche is in advanced microalloyed steels where simultaneous V+N addition is beneficial.
Major steel-producing nations with strong microalloyed steel sectors (China, India, Germany, Japan, South Korea) manufacture FeVN to supply domestic steel mills.
FeVN is commercially available from specialist ferroalloy producers and steelmaking raw material suppliers, but it is less common than standard FeV50 or FeV80.
Its use is growing in high-strength rebar and HSLA steel markets, especially where nitrogen control is critical.
Bottom line: FeVN is produced on demand and is regionally abundant where steelmakers need combined V+N microalloying, but globally it is a specialty product, not a mass commodity like plain ferrovanadium.
FeVN is an alloy, not a fixed chemical compound, so it is described by typical composition ranges (weight percent):
|
|
|
|
|
|
|
Strong carbide/nitride former, precipitation strengthening
|
|
|
5–25 % (some grades up to ~25 %)
|
Forms fine VN particles, enhances grain refinement
|
|
|
|
|
|
|
|
From production process, may influence dissolution

Example industrial grade: FeVN 60/15 → ~60 % V, ~15 % N, rest Fe.
In steel, the alloy supplies V and N atoms that combine to form vanadium nitride (VN) and possibly vanadium carbide (VC) particles in the solid steel matrix.
When FeVN is added to molten steel (usually during tapping or in a ladle furnace), it produces several important metallurgical effects:
A. Combined Precipitation Strengthening
Vanadium reacts with nitrogen to form fine, thermally stable VN particles dispersed in the steel.
These particles hinder dislocation movement, increasing yield strength and hardness without large losses in ductility.
B. Grain Refinement
VN particles pin austenite grain boundaries during heating, preventing grain growth.
After cooling, the steel has a finer ferrite/pearlite grain structure, which improves toughness, fatigue resistance, and ductility.
C. Improved Hardenability
Presence of VN raises the steel's hardenability, allowing deeper and more uniform hardening in thick sections during quenching.
D. Enhanced Weldability & Toughness
Controlled V+N additions improve strength while maintaining good weldability and resistance to brittle fracture, especially at low temperatures.
E. Efficient Microalloying
Using FeVN ensures the optimal V:N ratio for targeted precipitate formation, avoiding the need for separate vanadium and nitrogen additions.
Block form allows easy, precise dosing and uniform distribution in the melt.
