One of two abrasion-resistant grade steels offered here at SendCutSend, AR400 steel is formulated to take a massive amount of punishment and abuse.
Used in shooting range targets, armor plating, and quarry machinery, this material is ready to provide your projects with toughness and durability.
AR400 steel is designed to have excellent abrasion and impact resistance.
You’ll find it in everything from armor plating for Battlebots to bed linings for quarry dump trucks.
Laser cut AR400 plate shines with its low maintenance costs and its through-hardness, positioning it as an economical fit for large-scale mining operations and industries with high wear risk. This steel is three times stronger than mild steel and it can take almost any punishment you throw at it.
