What is MIL A 12560 Steel?
MIL A 12560 steel plate is a specialized, high-strength steel type, engineered to withstand high-velocity impacts and ballistic threats. MIL A 12560 is commonly referred to as RHA (Rolled Homogeneous Armor) steel. Frequently used in the manufacturing of armored military vehicles, tanks, and other defense equipment, its unique characteristics make it an ideal choice for military-grade applications.
Notable for its exceptional strength and toughness, MIL A 12560 steel is formulated to offer superior resistance against penetration and fragmentation, making it a reliable choice for safeguarding personnel and assets in combat environments.
Exhibiting excellent ballistic properties, it maintains its structural integrity even after multiple impacts. From armored personnel carriers to blast protection systems, the uses for MIL A 12560 steel are both diverse and critical. At Clifton Steel, we supply MIL A 12560 armor plate solutions that adhere to the highest quality standards. We offer a range of products in various thicknesses and sizes to meet specific project requirements.
