Iron Vanadium Alloy 65 Percent Vanadium Lumps Silver Colour For Spring Steel And Valve Steel Alloying
Iron vanadium alloy with 65% vanadium content, supplied as silver-grey metallic lumps, is a specialized ferroalloy designed to enhance the mechanical properties of high-performance steels, particularly spring steel and valve steel. Its balanced vanadium concentration offers a cost-effective solution for alloying while delivering critical metallurgical benefits.
Spring steel requires exceptional elasticity, fatigue resistance, and yield strength, while valve steel demands high-temperature strength, wear resistance, and resistance to creep. Vanadium addresses these needs through three primary mechanisms:
- Carbide Refinement: Forms fine vanadium carbides that increase hardness and strength without excessive brittleness
- Grain Refinement: Suppresses austenite grain growth for improved toughness and ductility
- Secondary Hardening: Provides precipitation hardening during tempering for high-temperature strength
- Cost efficiency compared to high-purity vanadium metal
- Optimal balance between deoxidizing capacity and ease of dissolution
- Controlled impurities with low levels of sulfur, phosphorus, and tramp elements
