Keluli Xar500
XAR500 steel is a high-performance abrasion resistant material with a hardness level of approximately 470–530 HBW. It is engineered for extreme wear conditions where maximum surface durability is required.
With a carefully balanced alloy composition and quenched and tempered structure, XAR500 provides excellent resistance to abrasion in mining, simen, keluli, and bulk handling industries.
Namun begitu, due to its high hardness, it requires proper fabrication techniques and is best used in applications where wear resistance is more critical than impact toughness.
- Penerangan
XAR500 steel adalah kekerasan tinggi, quenched and tempered wear-resistant steel designed for extreme abrasion conditions. It belongs to the premium-grade abrasion resistant steel family and is widely used in mining, Penggalian, pengeluaran simen, loji keluli, and heavy-duty material handling systems.
Compared with standard AR steels, XAR500 provides higher hardness, improved wear resistance, and longer service life in severe operating environments.
Chemical Composition of XAR500 Steel
XAR500 is an alloyed carbon steel with carefully controlled elements to achieve high hardness and toughness balance.
Unsur pengaloian biasa termasuk:
| unsur | Fungsi |
|---|---|
| Karbon (C) | Meningkatkan kekerasan dan kekuatan |
| Mangan (Mn) | Meningkatkan keliatan dan rintangan haus |
| Chromium (Cr) | Enhances abrasion and oxidation resistance |
| nikel (Dalam) | Meningkatkan keliatan impak |
| Molibdenum (Mo) | Stabilizes hardness and strength |
These elements work together to create a strong, wear-resistant microstructure after heat treatment.

XAR500 is designed for maximum abrasion resistance in severe wear environments.
Why XAR500 Has Excellent Wear Resistance
1. Kekerasan Permukaan Tinggi
The key performance feature of XAR500 is its very high hardness level:
- Strong resistance to cutting and gouging
- Reduced material loss under friction
- Extended service life in abrasive environments
2. Struktur Mikro Dipadamkan dan Dibaja
XAR500 is heat treated to form a fine martensitic structure:
- Pengagihan kekerasan seragam
- Rintangan yang lebih baik terhadap ubah bentuk permukaan
- Better structural stability under load
3. Pengoptimuman Aloi
Elements like chromium and molybdenum:
- Meningkatkan kestabilan rintangan haus
- Increase hardness retention
- Enhance performance under heavy load conditions
