En esta guía, we’ll cover everything from its chemical makeup to real-world success stories, so you can decide if it’s right for your needs.

1. Material Properties of Dillidur 400V: Why It’s So Durable

Dillidur 400V’s strength comes from its carefully balanced composition and unique properties. Let’s break it down into four key areas:

Composición química

Elalloying elements in Dillidur 400V work together to boost its wear resistance and toughness. Here’s a typical breakdown and what each element does:

Propiedades físicas

These properties affect how Dillidur 400V behaves in different environments (like temperature changes or magnetic handling):

• Densidad: ~7.85 g/cm³ (same as most carbon steels, so it’s easy to replace old parts without redesigning equipment).
• Conductividad térmica: ~44 W/(m·K) (dissipates heat well, which is key for high-friction parts like crusher liners).
• Coeficiente de expansión térmica: ~13 × 10⁻⁶/°C (minimizes warping when heated, keeping parts in shape).
• Capacidad calorífica específica: ~470 J/(kg·K) (handles temperature swings without damage, ideal for outdoor use).
• Propiedades magnéticas: Ferromagnético (works with magnetic tools for lifting or positioning parts in factories).

Propiedades mecánicas

These are the “workhorse” traits that make Dillidur 400V perfect for heavy-duty jobs:

• Resistencia a la tracción: ≥ 1,250 MPa (can handle extreme pulling forces without breaking).
• Fuerza de producción: ≥ 1,000 MPa (resists permanent bending or deformation under heavy loads).
• Dureza: 380–420 HBW (Brinell), ~40 HRC (Rockwell), or ~400 HV (Vickers)—hard enough to resist daily wear.
• Dureza al impacto: ≥ 30 J a -40°C (stays tough even in freezing conditions, so parts don’t crack in winter).
• Fuerza de fatiga: Resists damage from repeated stress (great for parts like conveyor belts that run nonstop).
• Resistencia a la abrasión: 2–3 times higher than standard structural steel (the main reason it lasts longer than regular steel parts).

Otras propiedades

• Resistencia a la corrosión: Moderado (works well in dry or slightly wet conditions; add a coating for rainy or humid environments).
• Soldabilidad: Bien (with proper preheating and low-hydrogen electrodes, it can be welded to other steels easily).
• maquinabilidad: Requires carbide tools (due to its hardness, but still manageable with the right equipment).
• Templabilidad: Excelente (the hard surface goes deep into the steel, not just a thin layer—so it doesn’t wear through fast).

2. Applications of Dillidur 400V: Where It Works Best

Dillidur 400V is used across industries where abrasion is a major problem. Here are the most common uses:

Industria Minera

Mining equipment faces constant wear from rocks, mineral, y suciedad. Dillidur 400V is ideal for:

• Cucharones de excavadora: Handles digging through hard rock without wearing down the bucket’s base.
• dientes de pala: Resists chipping and grinding when loading heavy ore.
• Revestimientos de trituradora: Protects the crusher’s inner walls from the impact of crushing stones.
• Revestimientos de molino: Lasts twice as long as standard liners, cutting down on replacement time.

Industria de la construcción

Construction sites involve moving gravel, suciedad, and debris—all of which wear down equipment. Dillidur 400V is used for:

• Bulldozer blades: Stands up to scraping against concrete or rocky soil.
• Loader buckets: Carries heavy loads of gravel without wearing thin.
• Dump truck beds: Prevents damage from sharp rocks or construction waste.
• Equipos de movimiento de tierras: Parts like rippers and scrapers stay functional longer.

Industria agrícola

Farm machinery deals with soil, crops, and debris. Dillidur 400V works for:

• Arados: Resists wear from tough soil or hidden rocks in fields.
• Gradas: Maintains sharpness for tilling season after season.
• Cosechadoras: Protects parts that handle grain and straw.
• Equipos de manipulación de granos: Prevents scratches on chutes that move grain.

Industria del reciclaje

Recycling plants process metal, plástico, and waste—all of which wear down equipment. Dillidur 400V is used for:

• trituradoras: Handles shredding metal or plastic without dulling.
• Trituradoras: Breaks down waste without damaging the crusher’s parts.
• Transportadores: Belt supports and guides resist wear from moving materials.
• Máquinas empacadoras: Presses waste into bales without wearing the machine’s plates.

Aplicaciones industriales

In factories and plants, Dillidur 400V protects equipment that moves or processes materials:

• Tolvas: Prevents clogging and wear from powders or granules (like cement or coal).
• caídas: Guides materials without scratching or wearing down.
• Placas de desgaste: Lines equipment to add a protective layer.
• Sistemas de tuberías: Transports abrasive materials (like sand) without leaks or damage.

3. Manufacturing Techniques for Dillidur 400V

Making Dillidur 400V requires precise steps to ensure its strength and wear resistance. Here’s how it’s done:

1. Proceso de fabricación de acero

• Horno de arco eléctrico (EAF): The most common method. Scrap steel is melted in an EAF, y alloying elements (like Cr and Mo) are added to reach the right composition.
• Horno de oxígeno básico (BOF): Used for large-scale production. El mineral de hierro se convierte en acero., then alloyed to meet Dillidur 400V’s specs.

2. Proceso rodante

• laminación en caliente: The steel is heated to ~1,100–1,200°C and rolled into plates of different thicknesses (from 3mm to 100mm). This shapes the steel and makes its grain structure stronger.
• laminación en frío: Optional for thin plates. It smooths the surface and increases hardness slightly, but hot rolling is more common for Dillidur 400V’s heavy-duty use.

3. Tratamiento térmico

This step is crucial for Dillidur 400V’s hardness and toughness:

• Temple: The hot-rolled steel is rapidly cooled in water or oil. This creates a hard, martensitic structure.
• Templado: The quenched steel is heated to ~250–350°C and cooled slowly. This reduces brittleness while keeping high hardness.
• Normalizando: Sometimes used before quenching to make the grain structure uniform, ensuring consistent performance.

4. Tratamiento superficial

• Granallado: Removes rust and scale from the surface, preparing it for welding or coating.
• Molienda: Creates a smooth surface for applications where precision is key (like conveyor parts).
• Revestimiento: Options include paint or galvanizing (for extra resistencia a la corrosión in wet environments).

5. Control de calidad

Every batch of Dillidur 400V is tested to meet standards:

• Chemical analysis: Uses spectrometry to check the levels of C, cr, Mes, y otros elementos.
• Mechanical testing: Includes tensile tests, hardness tests, and impact tests to verify strength and toughness.
• Non-destructive testing (END): Uses ultrasonic or magnetic particle testing to find hidden cracks or defects.
