Xar500 スチール
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, セメント, 鋼鉄, and bulk handling industries.
しかし, 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.
- 説明
XAR500 steel is a high-hardness, 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, 採石, セメント生産, 鉄鋼工場, 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.
代表的な合金元素には次のものがあります。:
| 要素 | 関数 |

XAR500 is designed for maximum abrasion resistance in severe wear environments.
Why XAR500 Has Excellent Wear Resistance
1. 高い表面硬度
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. 焼入れおよび焼き戻し後の微細構造
XAR500 is heat treated to form a fine martensitic structure:
- 均一な硬度分布
- Improved resistance to surface deformation
- Better structural stability under load
3. Alloy Optimization
Elements like chromium and molybdenum:
- Improve wear resistance stability
- Increase hardness retention
- Enhance performance under heavy load conditions
