En esta guía, desglosaremos sus propiedades clave, usos del mundo real, proceso de fabricación, and how it stacks up against other materials—so you can make smart decisions for your equipment.
1. Material Properties of Dillidur 500V
Dillidur 500V’s durability comes from its carefully crafted composition and well-balanced properties. Let’s explore each category:
Composición química
Elalloying elements in Dillidur 500V work together to boost wear resistance and toughness. Here’s what you need to know:
| Element | Role in Dillidur 500V Performance |
|---|---|
| Carbón (do) | Increases hardness by forming strong carbides, which resist scratches and daily abrasion. |
| Manganeso (Minnesota) | Enhances tensile strength and impact toughness, preventing brittle fractures. |
| Silicio (Y) | Aids in deoxidation during manufacturing and improves heat resistance for high-friction jobs. |
| Cromo (cr) | Creates hard chromium carbides in the steel matrix, boosting long-term wear resistance. |
| Molibdeno (Mes) | Improves high-temperature strength and makes welding easier by reducing crack risk. |
| Vanadio (V) | Refines the steel’s grain structure and forms hard carbides, increasing overall durability. |
| Níquel (En) | Boosts toughness, especially in cold environments—perfect for winter construction or northern mining. |
Propiedades físicas
These traits determine how Dillidur 500V behaves in different environments:
- Densidad: ~7.85 g/cm³ (same as most carbon steels, so it’s easy to swap with old parts without redesigning equipment).
- Conductividad térmica: ~43 W/(m·K) (dissipates heat well, ideal for parts like shredder blades that generate friction).
- Coeficiente de expansión térmica: ~12.8 × 10⁻⁶/°C (minimizes warping when heated, keeping parts in shape).
- Capacidad calorífica específica: ~465 J/(kg·K) (handles temperature swings, great for outdoor use in hot or cold climates).
- Propiedades magnéticas: Ferromagnético (works with magnetic lifting tools in factories or job sites).
Propiedades mecánicas
These are the “workhorse” features that make Dillidur 500V stand out for heavy-duty tasks:
- Resistencia a la tracción: ≥ 1,400 MPa (can handle extreme pulling forces without breaking).
- Fuerza de producción: ≥ 1,150 MPa (resists permanent bending or deformation under heavy loads).
- Dureza: 480–520 HBW (Brinell), ~50 HRC (Rockwell), or ~500 HV (Vickers)—hard enough to resist sharp rocks and debris.
- Dureza al impacto: ≥ 25 J a -40°C (stays tough in freezing weather, so parts don’t crack in winter).
- Fuerza de fatiga: Resists damage from repeated stress (perfect for conveyor belts or rotating parts that run nonstop).
- Resistencia a la abrasión: 3–4 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 paint or galvanized coating for rainy or humid environments).
- Soldabilidad: Bien (with preheating to 150–250°C and low-hydrogen electrodes, it can be welded to other steels easily).
- maquinabilidad: Requires carbide tools (due to its high hardness, but still manageable with the right equipment).
- Templabilidad: Excelente (the hard surface extends deep into the steel, not just a thin layer—so it doesn’t wear through quickly).
2. Applications of Dillidur 500V
Dillidur 500V is used across industries where abrasion is a major challenge. Here are its most common uses:
Industria Minera
Mining equipment faces constant wear from rocks, mineral, y suciedad. Dillidur 500V 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 2–3 times longer than standard liners, cutting replacement downtime.
Industria de la construcción
Construction sites involve moving gravel, suciedad, and debris—all of which wear down equipment. Dillidur 500V 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 500V 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 500V 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 500V 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 500V
Creating Dillidur 500V requires precise steps to ensure its strength and wear resistance. Here’s the process:
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 500V’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 4mm to 120mm). This shapes the steel and refines its grain structure for better strength.
- laminación en frío: Optional for thin plates. It smooths the surface and increases hardness slightly, but hot rolling is more common for Dillidur 500V’s heavy-duty use.
3. Tratamiento térmico
This step is critical for Dillidur 500V’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 ~280–350°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 500V 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.
