Could You Explain The Difference Between Ferro Silicon 75 And Ferro Vanadium 80?

Ferro silicon 75 and ferro vanadium 80 are two important ferroalloys used in the steelmaking and foundry industries. Buyers often compare ferro silicon 75 and ferro vanadium 80 when selecting alloying materials for steel production. As a China ferroalloy supplier and manufacturer, ZHEN AN INTERNATIONAL CO., LIMITED (ZhenAn) provides both products with stable quality and reliable delivery. In this article, we explain the difference between ferro silicon 75 and ferro vanadium 80, their applications, and why choosing a factory-direct supplier like ZhenAn ensures cost advantages and consistent supply.

Ferro Silicon 75

• Composition: silicon content about 75%, with iron and trace elements.
• Main function: deoxidizer, alloying agent, and inoculant in steelmaking and casting.
• Effect: improves strength, hardness, and oxidation resistance of steel.

Ferro Vanadium 80

• Composition: vanadium content about 80%, balance iron.
• Main function: used as an alloying agent to increase wear resistance and strength.
• Effect: refines grain structure, enhances toughness, and improves steel's resistance to fatigue.

The difference is that ferro silicon 75 is mainly for deoxidation and improving casting quality, while ferro vanadium 80 is mainly for strengthening and refining the grain structure of steel.

Ferro Silicon 75 Applications:

• Deoxidizer in steelmaking.
• Inoculant in cast iron production.
• Alloying additive in electrical steel and stainless steel.

Ferro Vanadium 80 Applications:

• Strengthening additive in high-strength low-alloy steel.
• Grain refiner in tool steels.
• Essential alloying material in aerospace, automotive, and energy sectors.
