Pelat Baja Ar400
AR400 and AR500 steel plates are both high-performance wear resistant materials, but they are designed for different working conditions. AR400 offers better toughness and easier fabrication, making it suitable for general industrial applications. AR500 provides significantly higher hardness and wear resistance, making it ideal for extreme abrasion environments.
- Keterangan
AR400 steel plate and AR500 steel plate are two of the most commonly used tahan abrasi (AR) Kenakan baja. Both are quenched and tempered steels designed for wear protection, but they differ significantly in kekerasan, kekerasan, sifat mampu bentuk, and application range.
Understanding the difference between AR400 and AR500 is important for selecting the right material for specific wear environments.
AR400 vs AR500 Steel Plate Comparison
| Milik | Pelat Baja AR400 | Pelat Baja AR500 |
|---|---|---|
| Kekerasan (PBR) | ~360–440 HB | ~470–540 HB |
| Ketahanan Aus | Sedang hingga tinggi | Sangat tinggi |
| Kekerasan | Lebih tinggi | Lebih rendah |
| Resistensi Dampak | Lebih baik | Sedang |
| Sifat mampu bentuk | Easier to cut, membengkokkan, dan mengelas | More difficult to process |
| Kehidupan Pelayanan | Bagus | Longer in high-abrasion conditions |
| Efisiensi Biaya | Lebih ekonomis | Higher cost but longer wear life |
1. Wear Resistance Difference
AR500 has significantly higher hardness than AR400, which directly improves its resistance to:
- Abrasi geser
- Sand and gravel wear
- Ore and mineral impact
- Continuous material flow erosion
Kesimpulan:
AR500 performs better in extreme wear environments, while AR400 is suitable for balanced conditions.
2. Toughness and Impact Resistance
AR400 has higher toughness, meaning it can better absorb impact energy without cracking. This makes it suitable for applications involving:
- Heavy shock loading
- Impact from rocks or machinery
- Dynamic structural stress
AR500, due to its higher hardness, is more brittle compared to AR400 and is less suitable for high-impact conditions.
3. Processing and Fabrication
AR400 is easier to process:
- Kemampuan las yang lebih baik
- Easier cutting and bending
- Lower risk of cracking during fabrication
AR500 requires more careful handling:
- Preheating often required for welding
- Higher tool wear during cutting
- Limited bending capability
4. Perbedaan Aplikasi
AR400 Applications
- Excavator buckets and wear parts
- Badan truk sampah
- Cement plant liners
- Mesin pertanian
- General mining equipment
AR500 Applications
- High-abrasion mining environments
- Crushers and grinding systems
- Heavy-duty hoppers and chutes
- Severe wear industrial zones
- Sistem penanganan material massal
5. Selection Principle
- Memilih AR400 when impact resistance, kemampuan las, and balanced performance are required
- Memilih AR500 when maximum wear resistance and extended service life are the priority
