Ferro Vanadium 80 is a ferroalloy containing about 80% vanadium and is one of the commonly used alloy additives in the steel industry. Its main characteristics and applications are as follows:
ferro vanadium 80 basic composition and properties
1. Composition
- Vanadium content: about 78%~82%.
- Iron content: Residual, usually about 18%~22%.
- May contain a small amount of impurities (such as carbon, silicon, aluminum, phosphorus, etc.).
2. Physical Properties
- Appearance: gray to silver-gray metallic lump or powder.
- Density: about 6.7~7.0 g/cm³.
- Melting point: about 1650 degree , varies due to fluctuations in composition.
ferro vanadium 80 production process
Ferrovanadium 80 is usually produced by the following methods:
- Aluminum Thermal Reduction: Using vanadium ores (e.g. vanadium-titanium magnetite) or vanadium pentoxide (V₂O₅) and aluminum powders at high temperatures to obtain ferrovanadium alloys with high vanadium content.
- Carbon Thermal Reduction: Made by reducing vanadium ore with carbon and combining it with iron in an electric arc furnace.
ferro vanadium 80 major applications
1. Iron and steel industry
- Used as alloy additives, mainly used in the production of high-strength low alloy steel (HSLA steel), tool steel, stainless steel, heat-resistant steel and so on.
- Vanadium significantly increases the strength, toughness and wear resistance of steel, while improving its corrosion resistance and weldability.
- Vanadium forms carbides in steel, which can refine grain size and inhibit grain boundary segregation, thus improving the mechanical properties of steel.
2. Foundry industry
- Used in the modification of cast iron to enhance the hardness and wear resistance of castings.
3. Other uses
- Preparation of certain special materials or new alloys.
ferro vanadium 80 advantages and Characteristics
- High Vanadium Content: Ferro Vanadium 80 provides vanadium more efficiently than other low content ferro vanadiums (e.g. FeV50), reducing the amount added.
- Stability: Low impurity content makes it suitable for high quality steel production.
