Ar-Plattenstahl
AR plate steel includes a range of wear-resistant grades such as AR400, AR450, AR500, and extended high-hardness grades like AR550 and AR600. These materials are defined by increasing hardness levels, offering progressively higher wear resistance for more demanding working conditions.
- Beschreibung
AR-Plattenstahl (Abriebfeste Stahlplatte) is a group of quenched and tempered wear-resistant steels designed to withstand sliding abrasion, Auswirkungen, and heavy material wear. Es wird häufig im Bergbau eingesetzt, Konstruktion, Landwirtschaft, Zement, und Schüttguttransportindustrien.
AR grades are mainly defined by Brinellhärte (HBW), which directly reflects wear resistance performance. The most common AR plate steel grades include AR400, AR450, und AR500.
AR Series Wear Resistant Steel Grades
| Grad | Härte (HBW) | Verschleißfestigkeitsstufe | Zähigkeit | Hauptmerkmale | Typische Anwendungen |
|---|---|---|---|---|---|
| AR400 | ~360–440 | Medium | Gut | Ausgewogene Verschleißfestigkeit und Zähigkeit, easy to process | Baumaschinen, Bergbauausrüstung, Strukturelle Verschleißteile |
| AR450 | ~430–480 | Hoch | Medium | Improved abrasion resistance with higher hardness | Heavy-duty equipment, Liner, Muldenkipperaufbauten |
| AR500 | ~470–540 | Sehr hoch | Mittel-niedrig | High hardness for severe abrasion environments | Mining systems, Brecher, Strapazierfähige Einlagen |
Extended AR Grades (Special Applications)
Some manufacturers also produce higher or specialized AR grades:
| Grad | Härte (HBW) | Hauptmerkmale | Typische Anwendungen |
|---|---|---|---|
| AR550 | ~520–600 | Extrem hohe Verschleißfestigkeit | Severe mining and crushing environments |
| AR600 | ~570–650 | Maximum hardness level | Extreme abrasion and impact systems |
Performance Characteristics of AR Plate Steel
AR steel is produced through Wärmebehandlung durch Abschrecken und Anlassen, resulting in a hardened martensitic structure. This provides:
- High surface hardness for abrasion resistance
- Je nach Sorte gute Schlagfestigkeit
- Stable performance under sliding wear conditions
- Controlled weldability with proper procedures
Mit zunehmender Härte, Die Verschleißfestigkeit verbessert sich, while toughness and formability slightly decrease.
Grade Selection Principle
- AR400 → General industrial wear applications with balanced performance
- AR450 → Medium to heavy wear conditions with improved durability
- AR500 → High abrasion environments such as mining and bulk handling
- AR550–AR600 → Extreme wear and impact applications
