What Is Ferro Vanadium 50 10-220mm?

Ferro Vanadium 50 10-220mm refers to a specific grade and size specification of ferrovanadium alloy, where:

"Ferro Vanadium 50" indicates a minimum 50% vanadium (V) content (balance: iron and trace elements like silicon, aluminum, carbon).

"10-220mm" defines the lump size range of the alloy, with pieces measuring between 10 millimeters (0.4 inches) and 220 millimeters (8.7 inches) in diameter.

This product is a cornerstone of bulk steelmaking, valued for its cost-effectiveness and suitability for large-scale alloying. Below, we break down its composition, uses, advantages, and why it's a preferred choice for industrial buyers.

Composition & Specifications of Ferro Vanadium 50 10-220mm

Chemical Composition

A typical Ferro Vanadium 50 10-220mm grade adheres to these standards:

Element	Content Range	Purpose
Vanadium (V)	≥50%	Primary alloying element (strengthens steel).
Iron (Fe)	Balance (~48-50%)	Carrier metal for vanadium addition.
Silicon (Si)	≤2.0%	Improves deoxidation and fluidity.
Aluminum (Al)	≤1.5%	Enhances deoxidation and grain refinement.
Carbon (C)	≤0.2%	Residual from production (minimized for steel purity).
Sulfur (S)/Phosphorus (P)	≤0.04%/≤0.05%	Controlled to avoid steel brittleness.

Physical Specifications

Size Range: 10–220mm lumps (customizable upon request).

Form: Irregularly shaped pieces, easy to handle with standard industrial equipment (e.g., conveyor belts, charging buckets).

Packaging: Typically packed in 1-tonne bags or bulk containers to prevent moisture absorption.

Key Uses of Ferro Vanadium 50 10-220mm

With its balanced vanadium content and practical lump size, this grade is ideal for high-volume, cost-sensitive steelmaking applications:

1. High-Strength Low-Alloy (HSLA) Steels

Used in rebar, bridge beams, and pipeline steels (e.g., API X52-X70), where 0.1–0.3% vanadium addition enhances strength (yield strength up to 450 MPa) and reduces weight by 10–15%.

2. General Construction Steel

Added to structural steel (e.g., Q355B) to improve tensile strength and toughness, ensuring durability in buildings, railways, and stadiums.

3. Cast Iron Alloying

Inoculates gray iron to prevent "chill" (hard, brittle iron carbides) and promote uniform graphite distribution, improving machinability.

Advantages of Ferro Vanadium 50 10-220mm

1. Cost-Effective for Bulk Applications

The 50% vanadium content strikes a balance between affordability and alloying efficiency. It is cheaper per tonne than higher grades (e.g., FeV80) and avoids overpaying for vanadium in applications where extreme precision is unnecessary.

2. Easy Handling & Compatibility

The 10–220mm lump size is optimized for:

Furnace Charging: Fits standard charging buckets and conveyor systems.

Uniform Dissolution: Large enough to avoid dusting during handling, yet small enough to dissolve quickly in molten steel.

3. Reliable Supply & Scalability

Produced in large batches, this grade ensures consistent supply for steel mills with high throughput (e.g., 1,000+ tonnes/month).
