Iron Vanadium 75 Grade Alloy Block Black Silver For Armour Plate Steel And High Strength Construction Use

Iron Vanadium 75 Grade Alloy Block, characterized by its striking black-silver metallic sheen, is a high-performance FeV alloy​ (ferrovanadium) designed to meet the extreme demands of armour plate steel​ and high-strength construction applications. With ~75% vanadium content, this Iron Vanadium Alloy​ (often labeled FeV75, Ferrovanadium 75, or Vanadium Iron Alloy 75) bridges the gap between mid-range and premium ferrovanadium grades, delivering a unique balance of potency, cost-efficiency, and reliability. Its block form (irregular chunks, 20–80 mm) ensures easy handling in large-scale steelmaking, while its optimized composition enhances critical properties like hardness, toughness, and ballistic resistance.

Vanadium’s ability to form fine, thermally stable carbides (VC) and refine austenite grains is amplified in the 75% grade, making it ideal for applications requiring:

• Ballistic Resistance: In armour plate steel, VC particles act as micro-armor, dispersing kinetic energy from projectiles and preventing penetration.

• Load-Bearing Capacity: In construction steels (e.g., bridge girders, high-rise columns), vanadium strengthens the matrix, enabling thinner sections without sacrificing strength—reducing material usage and costs.

• Fatigue Resistance: Refined grains and carbide networks resist crack propagation, critical for structures subjected to cyclic loads (e.g., bridges, cranes).

The alloy’s black-silver hue reflects its controlled oxidation during production, signaling:

• High Purity: Minimal surface impurities (S ≤ 0.04%, P ≤ 0.03%) ensure clean steel with fewer inclusions.

• Dense Structure: Low porosity reduces dissolution time in molten steel, ensuring uniform vanadium distribution.

Armour plate steel demands exceptional hardness (HRC 50–55), toughness, and resistance to ballistic impact. Iron Vanadium 75 Grade excels here by:

• Enhancing Hardness: VC particles (≤1 µm) increase surface hardness by 20–30% compared to non-alloyed armour steel.

• Improving Toughness: Grain refinement prevents brittle fracture, allowing armour to absorb impact energy without shattering.

• Corrosion Resistance: Vanadium’s interaction with alloying elements (e.g., Cr, Ni) enhances passivation, extending service life in harsh environments (e.g., military vehicles, coastal defenses).

Example: A defence contractor producing rolled homogeneous armour (RHA) for armored personnel carriers uses FeV75 blocks to achieve NATO-standard ballistic protection while keeping plate weight manageable.

In construction, the goal is to build lighter, stronger, and more durable structures. Iron Vanadium 75 Grade enables this by:

• Increasing Yield Strength: Vanadium additions (0.2–0.5%) boost yield strength by 15–25% in structural steels (e.g., ASTM A992, EN 10025-6).

• Reducing Section Thickness: Higher strength allows engineers to design thinner beams and columns, cutting material costs by 10–15% without compromising safety.

• Enhancing Weldability: Low impurity levels minimize hydrogen-induced cold cracking (HICC), ensuring strong, defect-free welds in critical joints (e.g., skyscraper frameworks, stadium roofs).

Example: A construction firm building a cable-stayed bridge uses FeV75-alloyed high-strength steel for the main girders, reducing total steel tonnage by 12% while meeting seismic safety standards.

• Cost-Effective Potency: More affordable than FeV80 (80% V) but nearly as effective, making it ideal for large-scale projects.

• Versatility: Performs equally well in military and civilian applications, from tank armor to high-rise construction.

• Reliability: Consistent composition and block form ensure predictable results in batch production.

Iron Vanadium 75 Grade Alloy Block, with its black-silver finish and optimized 75% vanadium content, is a game-changer for armour plate steel and high-strength construction. By enhancing hardness, toughness, and load-bearing capacity, it enables the production of lighter, safer, and more durable materials—meeting the dual demands of military protection and modern infrastructure. For manufacturers seeking a balance of performance and cost, this alloy block is an indispensable solution.

Q: What is ferrovanadium?  
A: Ferrovanadium is an iron–vanadium alloy used as a master alloy to introduce vanadium into steel and cast iron for strengthening and toughening.  

Q: Ferrovanadium definition and primary function?  
A: It is an alloy of iron and vanadium, primarily used to add controlled amounts of vanadium to alloys, improving strength, wear resistance, and hardenability.  

Q: Difference between ferrovanadium and vanadium metal?  
A: Ferrovanadium is an Fe–V alloy (typically 40–80% V) for adding vanadium to other metals; vanadium metal is nearly pure V, used in superalloys and chemicals.  

Q: Common types of ferrovanadium grades – FeV40, FeV60, FeV80?  
A: FeV40 (~40% V), FeV60 (~60% V), FeV80 (~80% V); number indicates approximate vanadium content.  

Q: Composition of ferrovanadium – typical vanadium content?  
A: Vanadium content varies by grade; typical ranges 40–80%, balance mainly iron with minor impurities (Al, Si, C).  

Q: How is ferrovanadium produced?  
A: Produced by aluminothermic or silicon reduction of vanadium pentoxide mixed with iron in an electric furnace or crucible.  

Q: Ferrovanadium manufacturing process steps?  
A: Mix V₂O₅ with iron reductant, heat in furnace to initiate exothermic reaction, melt, cast into lumps or grind to powder.  

Q: Raw materials for ferrovanadium production – vanadium pentoxide, iron ore?  
A: Mainly vanadium pentoxide (V₂O₅) and iron (scrap or ore) as reductant and base metal.
