The NM series wear plate steel provides a complete hardness range from NM360 to NM600, covering applications from light industrial wear to extreme mining conditions. Lower grades focus on toughness and versatility, while higher grades prioritize maximum abrasion resistance.
- 설명
NM series wear plate steel is the most widely used Chinese wear resistant steel standard, designed for different levels of abrasion and impact conditions. The series mainly includes NM360, NM400, NM450, NM500, NM550, 그리고 NM600. Each grade is defined by its hardness level and application environment, allowing users to select the most suitable material based on wear intensity and service conditions.
NM Series Wear Plate Steel Comparison
| 등급 | 경도 (HBW) | 내마모성 수준 | 인성 | 주요특징 | 일반적인 응용 분야 |
|---|---|---|---|---|---|
| NM360 | 330–390 | 기초적인 | 높은 | Good balance of toughness and wear resistance | Light mining equipment, general machinery, 구조적 마모 부품 |
| NM400 | 380–460 | 중간 | 좋은 | Most widely used standard grade | 덤프트럭 차체, 굴삭기 버킷, 시멘트 공장 라이너 |
| NM450 | 430-500 | 높은 | 중간 | Improved wear resistance and service life | 중장비 광산, high-impact wear areas |
| NM500 | 470-550 | 매우 높음 | Medium-low | Strong abrasion resistance, reduced deformation | 분쇄기, ore handling systems, 튼튼한 라이너 |
| NM550 | 520-600 | 극심한 | 낮추다 | Ultra high hardness for severe wear | 광산 분쇄기, extreme abrasion conditions |
| NM600 | 570-650 | 최고 | 낮추다 | Highest hardness in NM series | High-impact crushing systems, extreme wear environments |
Performance Trend in NM Series
- Hardness increases from NM360 to NM600
- Wear resistance improves gradually with higher grades
- Toughness decreases slightly as hardness increases
- Weldability becomes more demanding at higher grades
Key Selection Logic
- NM360–NM400 → Suitable for general industrial and light wear conditions
- NM450–NM500 → Standard choice for mining and construction machinery
- NM550–NM600 → Used for extreme abrasion and high-impact environments
미세구조 특성
All NM series wear plates are produced through quenching and tempering processes, forming a martensitic structure. 이는 다음을 보장합니다.:
- 높은 표면 경도
- Controlled toughness balance
- Stable wear resistance under impact and abrasion
- 열악한 환경에서도 긴 서비스 수명
