Menu
One of two abrasion-resistant grade steels offered here at SendCutSend, AR400 is the one you need for taking damage. Lots of it. Daily.
Used in shooting range targets, armor plating, and quarry machinery, this material is ready to provide your projects with toughness and sustainable depreciation on your stuff while also having accessible entry costs.

Impact Resistant
AR400 Steel for fortress-like durability
AR400 is made with one goal in mind: taking a beating–as its job. While technically it’s also for abrasion resistance, like we mentioned above, there are other grades in the series that better fit that goal. So this beauty was given superior impact resistance to handle diverse projects that didn’t revolve solely around resistance to abrasion.
You’ll find it in armor plating for Battlebots and in bed linings for quarry transport equipment just to give you a range of applications.
Where AR400 steel shines is in 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. It’s three times stronger than mild steel and it can take whatever punishment you throw at it.
