AR 400 (ALGOTUF 400 / BRINAR 400)
AR400 is a high-hardness, abrasion-resistant steel grade designed for use in high-wear industrial environments. The “AR” stands for “Abrasion Resistant,” and the “400” refers to its typical Brinell hardness value of approximately 400 HBW.
- Not intended for structural use
- Truck bed liners
- Gates
AR400 is a quenched and tempered, through-hardened alloy steel. Its high hardness makes it extremely resistant to wear and tear, which is why it is the material of choice for equipment that must endure constant sliding abrasion and impact from materials like rocks, ore, and sand.
