A514 AR400 abrasion resistant steel plate is a good candidate for some processing techniques. This material is characterized by a smooth, dark scale finish with a hardened surface. While not a good candidate for forming and machining, AR400 plate is suitable for welding. Intended for moderate wear applications, common uses include contact surfaces, hoppers, cement mixer drums and fins, and shooting targets. ASTM A514 is the standard specification for high yield, quenched and tempered alloy steel plate, suitable for welding.
400 Brinnel hardness. Extremely tough. Too hard to shear. Abrasion resistant.
