What are the differences between ferrovanadium 80 and ferrovanadium 40?

Ferrovanadium 80 and ferrovanadium 40 are both members of the FeV alloy family, but they differ significantly in vanadium content, metallurgical effect, typical applications, and cost.

• FeV40 contains more iron and less vanadium, so larger quantities are needed to achieve a given vanadium level in steel.
• FeV80 has a much higher vanadium concentration, meaning only small additions are needed for strong effects, and it yields finer, more numerous VC particles.
• The high vanadium content in Ferrovanadium 80 also increases its melting behavior impact, often requiring tighter process control.

• In terms of strengthening, ferrovanadium 80 provides maximum carbide precipitation, enhancing high‑temperature performance and wear resistance far beyond what ferrovanadium 40 can achieve.
• Ferrovanadium 40 is sufficient for applications where extreme hardness is unnecessary but some toughness improvement is desired at lower material cost.
