Plat Haus Tahan Lelasan
Abrasion resistant wear plates are available in multiple international grade systems including AR, Hardox, NM, Xar, and EH series. Each system offers different hardness levels and performance balances for specific industrial environments.
- Penerangan
Abrasion resistant wear plates are high-hardness steel materials specifically designed to resist friction, kesan, and abrasive wear in severe industrial environments. These steels are widely used in mining, pengeluaran simen, jentera pembinaan, sistem kitar semula, dan peralatan pengendalian bahan berat.
Internationally, abrasion resistant steels are classified by hardness level, alloy system, or regional standards. Different countries and manufacturers use different grade naming systems, but most materials are designed around the same principle: achieving a balance between hardness, keliatan, dan kebolehkimpalan.
1. Siri AR (North American Standard)
The AR series is one of the most widely recognized international abrasion resistant steel systems.
“AR” bermaksud Tahan Lelasan.
| Gred | Anggaran Kekerasan | Ciri-ciri Utama |

| AR400 | ~400 HB | Good wear resistance and weldability |
| AR450 | ~450 HB | Rintangan lelasan yang lebih baik |
| AR500 | ~500 HB | High wear resistance for severe conditions |
| AR600 | ~600 HB | Rintangan haus yang melampau, kebolehbentukan terhad |
Aplikasi Biasa
- Pelapik trak perlombongan
- Kapal penghancur
- Pelongsor penghantar
- Baldi penggali
2. Hardox Series (Sweden)
Hardox is a globally recognized wear plate system developed for high-performance abrasive environments.
| Gred | Kekerasan | Ciri-ciri |
|---|---|---|
| Hardox 400 | ~400 HB | Keliatan yang seimbang dan rintangan haus |
| Hardox 450 | ~450 HB | Improved service life |
| Hardox 500 | ~500 HB | Rintangan lelasan yang sangat baik |
| Hardox 550/600 | Kekerasan yang sangat tinggi | Persekitaran haus yang melampau |
Ciri-ciri
- Rintangan hentaman yang sangat baik
- High toughness despite hardness
- Good processing and welding capability
Aplikasi Biasa
- Badan trak dump
- Peralatan perlombongan berat
- Industrial wear liners
3. Siri NM (China Standard)
The NM series is one of the most common wear plate systems used in China.
“NM” generally refers to wear resistant steel plate.
| Gred | Anggaran Kekerasan | Penggunaan utama |
|---|---|---|
| NM360 | ~360 HB | General wear conditions |
| NM400 | ~400 HB | Perlombongan dan pembinaan |
| NM450 | ~450 HB | Pemakaian sederhana berat |
| NM500 | ~500 HB | Severe abrasion conditions |
Ciri-ciri
- Similar performance to AR grades
- Widely used in industrial fabrication
- Good cost-performance balance
4. XAR Series (Jerman)
XAR wear plates are European high-hardness abrasion resistant steels.
| Gred | Kekerasan | Ciri-ciri |
|---|---|---|
| XAR400 | ~400 HB | Rintangan haus yang baik |
| XAR450 | ~450 HB | Increased abrasion performance |
| XAR500 | ~500 HB | Severe wear applications |
Aplikasi
- peralatan simen
- Earthmoving machinery
- Sistem pengendalian bahan pukal
5. JFE EH Series (Jepun)
Japanese wear-resistant steels are known for stable quality and impact resistance.
| Gred | Kekerasan | Ciri-ciri |
|---|---|---|
| EH360 | ~360 HB | Kebolehkimpalan yang baik |
| EH400 | ~400 HB | Pakaian dan ketangguhan seimbang |
| EH500 | ~500 HB | Rintangan haus yang tinggi |
Kegunaan Biasa
- Jentera perindustrian
- Steel mill liners
- Peralatan perlombongan
6. Keluli Pakai Mangan Tinggi (MN13)
Unlike quenched wear plates, Mn13 is a work-hardening wear steel.
Ciri-ciri
- Surface hardens under impact
- Rintangan hentaman yang sangat baik
- Good for high-impact wear conditions
Aplikasi
- Rahang penghancur
- Lintasan kereta api
- Impact liners
7. Comparison of Major Wear Plate Grades
| Grade System | Julat Kekerasan | Kelebihan Utama |
|---|---|---|
| Siri AR | 400–600 HB | International standard recognition |
| Hardox | 400–600 HB | High toughness and premium quality |
| Siri NM | 360–500 HB | Cost-effective industrial use |
| XAR Series | 400–500 HB | European engineering applications |
| Mn13 Keluli | Pengerasan kerja | Rintangan hentaman tinggi |
8. Selection Considerations
Different abrasion resistant wear plates are selected based on:
- Jenis haus (gelongsor, kesan, mencungkil)
- Tahap kekerasan yang diperlukan
- Weldability requirements
- Processing complexity
- Persekitaran perkhidmatan
Higher hardness usually improves wear resistance, while lower hardness grades often provide better toughness and easier fabrication.
