What is AR500 Plate?
AR500 Plate is a high-strength, abrasion-resistant steel plate with a nominal Brinell Hardness of 500 HBW. The “AR” stands for Abrasion Resistant, and the “500” refers to the hardness level — making it suitable for applications involving extreme wear, impact, and sliding contact.
Key Features of AR500 Steel Plate:
- Brinell Hardness: ~500 HB (typically ranges 470–540 BHN)
- Tensile Strength: ~200,000 psi
- Excellent Wear Resistance: Outperforms mild steel by 4–6x
- Good Formability: Can be cold formed with care
- Limited Weldability: Pre- and post-weld precautions recommended
- Available Thicknesses: 3 mm to 80 mm or more
- Available Forms: Sheets, rolled plates, and cut shapes (targets, liners, etc.)
What is AR500 Used For?
Due to its extreme hardness and durability, AR500 plate is used in:
- Ballistic Armor Plates (Level III and IV protection)
- Shooting Range Targets (gong, silhouette, and dueling tree targets)
- Mining Equipment (liner plates, buckets, and chutes)
- Heavy Dump Trucks (body linings and floor panels)
- Agriculture Machinery (plows, tillers, drag plates)
- Earthmoving Equipment (excavator arms, blades, and guards)
- Defense Structures (armored walls, vehicles, bunkers)
Technical Properties of AR500 Steel
| Property | Value (Typical) |
|---|---|
| Brinell Hardness (BHN) | 470–540 |
