NFV® — FERROVANADIUM NITRIDE
NFV® — FERROVANADIUM NITRIDE
VN-α-Fe, melted/sintered
It is a composite alloy based on vanadium nitride and iron (VN-α-Fe). Available in two forms: as a melted material with maximum density or as a sintered composition with the highest nitrogen content

ABOUT THE MATERIAL

Purpose: Microalloying of structural, rail, and tool steels; replacement/optimization of ferrovanadium.
Effect: Increased strength and impact toughness, low operating melting temperature (~1450°C), high density, absence of open porosity

Designed for nitrogen alloying of vanadium-containing steels used in the manufacture of building structures, rails, tools, etc. Key benefits: low melting temperature (~1450°C); high density (6.0-6.5 g/cm³ for melted material); absence of open porosity; high compressive strength of lumps (over 200 MPa); available in various fractions tailored to customer requirements
