Fe Vanadium 70 Grade Briquette Dark Silver Used In Automotive Gear Steel And Shaft Manufacturing

Fe Vanadium 70 Grade Briquette, with its distinctive dark silver luster, is a high-performance Iron Vanadium Alloy​ (often labeled FeV70, Ferrovanadium 70, or Vanadium Iron Alloy 70) engineered to meet the exacting demands of automotive gear steel​ and shaft manufacturing. Containing ~70% vanadium, this FeV alloy​ is optimized for applications requiring exceptional fatigue resistance, wear resistance, and dimensional stability—critical properties for components like transmission gears, drive shafts, and axle shafts that endure cyclic loading and high stress. Its briquette form (compact, pillow-shaped blocks, 50–100 mm) ensures easy handling, minimal dust, and uniform dosing in steelmaking processes, making it a preferred choice for automotive suppliers and steel mills alike.

Automotive gear steels (e.g., 20MnCr5, 18CrNiMo7-6) and shaft materials (e.g., SAE 4140, 4340) require a fine balance of strength, toughness, and fatigue resistance to withstand millions of stress cycles without failure. Fe Vanadium 70 Grade delivers this through three key mechanisms:

Vanadium’s ability to form fine, uniformly distributed vanadium carbides (VC) and refine austenite grains is critical for reducing fatigue crack initiation. In gear steels, VC particles act as barriers to dislocation movement, delaying crack propagation and increasing the number of cycles to failure by 30–50% compared to non-alloyed steels. This is essential for transmission gears, which experience repeated tooth contact stresses.

The high vanadium content (70%) in FeV70 promotes dense VC networks, enhancing surface hardness (by 15–25%) and wear resistance. For drive shafts and axle shafts, this translates to reduced friction, minimized scoring, and longer service life—even under high torque and abrasive conditions.

Vanadium’s grain-refining effect ensures a consistent microstructure throughout the component, preventing distortion during heat treatment (e.g., carburizing, quenching). This is crucial for precision-machined gears and shafts, where tight tolerances (±0.01 mm) are required for proper fit and function.

The dark silver color of FeV70 briquettes indicates a dense, low-porosity structure with minimal surface oxidation, reflecting high purity (S ≤ 0.03%, P ≤ 0.02%) and controlled production. The briquette form offers distinct benefits for automotive steelmaking:

• Low Dust Generation: Compact shape reduces airborne particles, improving workplace safety and minimizing material loss.

• Uniform Dosing: Consistent size and weight enable precise addition to electric arc furnaces (EAF) or ladle furnaces, ensuring uniform vanadium distribution.

• Ease of Handling: Briquettes are stackable and compatible with automated feeding systems, streamlining production in high-volume steel mills.

• Transmission Gears: Bevel gears, helical gears, and synchronizer rings in manual/automatic transmissions, where fatigue resistance and wear resistance are paramount.

• Drive Shafts & Axle Shafts: Components transmitting torque from the engine to wheels, requiring high strength and dimensional stability under torsional stress.

• Differential Components: Ring gears and pinion gears, which demand resistance to pitting and scoring from constant meshing.

• Cost-Effective Potency: More affordable than FeV80 (80% V) but nearly as effective in carbide formation, making it ideal for high-volume automotive steel production.

• Automotive-Grade Purity: Ultra-low impurities prevent defects like inclusions and hot shortness, ensuring compliance with OEM standards (e.g., GM, Volkswagen, Toyota).

• Process Compatibility: Briquette form integrates seamlessly into existing steelmaking workflows, requiring no major equipment modifications.

Fe Vanadium 70 Grade Briquette (dark silver) is a cornerstone of modern automotive steelmaking, enabling the production of gears and shafts that meet the industry’s toughest performance and reliability standards. By enhancing fatigue resistance, wear resistance, and dimensional stability, it helps automotive suppliers reduce warranty claims, extend component lifespan, and optimize manufacturing efficiency. For manufacturers seeking a balance of performance, cost, and process adaptability, FeV70 briquettes are an indispensable solution.
