Piastra antiusura con riporto duro
Custom Hardfacing Wear Plates allow industries to choose the best base steel and overlay material for their specific wear and impact requirements.
By adjusting base steel grade, overlay alloy, spessore, and plate size, engineers can achieve maximum durability, tenacità, and cost efficiency in extreme industrial environments.
- Descrizione
Hardfacing Wear Plates are steel plates coated with a wear-resistant hardfacing layer through overlay welding.
La combinazione di sovrapposizione dura E base in acciaio resistente makes these plates ideal for minerario, cemento, energia, e industrie di movimentazione dei materiali, where equipment faces severe abrasion and impact.
Customizing the materials of both the overlay and base allows engineers to optimize resistenza all'usura, tenacità, and service life for specific industrial applications.
Base Steel Materials
The base steel provides structural support, tenacità all'impatto, and welding compatibility. Common options include:
| Materiale | Proprietà | Applicazioni |
|---|---|---|
| Q235 / Acciaio dolce | Buona saldabilità, moderate toughness | Light to medium wear areas |
| NM400 / AR400 | High toughness, moderata resistenza all'usura | Mining hoppers, cade, alimentatori |
| AR450 / NM450 | Higher hardness and toughness | Fodere del frantoio, bucket edges, impact zones |
| NM500 / AR500 | Extreme wear resistance and impact toughness | High abrasion and impact areas |
Base steel selection depends on equipment load, impact intensity, and operating conditions.
Hardfacing Overlay Materials
The overlay layer provides resistenza all'abrasione. Common materials include:
| Overlay Material | Durezza (HRC) | Caratteristiche | Applicazioni |
|---|---|---|---|
| Carburo di cromo (CrC) | 58–65 | Excellent sliding wear resistance, elevata durezza | Fodere del frantoio, slurry chutes, fodera per secchi |
| High Carbon Steel Alloy | 50–60 | Good abrasion and moderate impact resistance | Light to medium wear applications |
| Carburo di tungsteno | 60–65 | Estrema resistenza all'usura, brittle | Small high-wear parts, precision surfaces |
| Cobalt-Based Alloy | 60–64 | Abrasion and heat-resistant | Specialized mining and power equipment |
Overlay selection depends on abrasion severity, carico d'impatto, and environmental conditions.
