AR400 と AR500 スチールの違い
何をするのか “AR” 平均?
“AR” のために 耐摩耗性, 磨耗に耐えるように設計された指示鋼.
Hardness Comparison
- AR400 Steel: Has a hardness of 400 Brinell.
- AR500スチール: Features a higher hardness of 500 Brinell.
Both are significantly harder than mild steel (130 Brinell) or structural steel (まで 200 Brinell).
アプリケーション
- Abrasion-Heavy Surfaces:
- Used in environments like the bottom of dumper trucks, where constant wear occurs.
- Shooting Targets:
- Commonly used for steel targets due to its high hardness, which minimizes pitting.
- Armor Applications:
- Hardness ranges from 350 に 600+ Brinell for armor-grade steel. These are specially engineered to combine hardness with toughness.
まとめ
AR400 and AR500 differ mainly in hardness, with AR500 offering greater durability for demanding applications. Both are ideal for uses requiring abrasion resistance, but specific needs should guide the choice.
