Ar 플레이트 스틸
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.
- 설명
AR 플레이트 스틸 (내마모성 강판) is a group of quenched and tempered wear-resistant steels designed to withstand sliding abrasion, 영향, and heavy material wear. 광산에서 널리 사용됩니다., 건설, 농업, 시멘트, 및 벌크 자재 취급 산업.
AR grades are mainly defined by 브리넬 경도 (HBW), which directly reflects wear resistance performance. The most common AR plate steel grades include AR400, AR450, and AR500.
AR Series Wear Resistant Steel Grades
| 등급 | 경도 (HBW) | 내마모성 수준 | 인성 | 주요특징 | 일반적인 응용 분야 |
|---|---|---|---|---|---|
| AR400 | ~360~440 | 중간 | 좋은 | 균형잡힌 내마모성과 인성, easy to process | 건설 기계, 광산 장비, 구조적 마모 부품 |
| AR450 | ~430–480 | 높은 | 중간 | Improved abrasion resistance with higher hardness | Heavy-duty equipment, 라이너, 덤프 트럭 시체 |
| AR500 | ~470~540 | 매우 높음 | Medium-low | High hardness for severe abrasion environments | Mining systems, 크러셔, 마모가 심한 라이너 |
Extended AR Grades (Special Applications)
Some manufacturers also produce higher or specialized AR grades:
| 등급 | 경도 (HBW) | 주요 특징 | 일반적인 응용 분야 |
|---|---|---|---|
| AR550 | ~520–600 | 매우 높은 내마모성 | 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 담금질 및 템퍼링 열처리, resulting in a hardened martensitic structure. This provides:
- High surface hardness for abrasion resistance
- 등급에 따라 내충격성이 우수함
- Stable performance under sliding wear conditions
- Controlled weldability with proper procedures
경도가 높아지면서, 내마모성이 향상됩니다., 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
