Latham Steel is a trusted manufacturer and supplier based in Hamilton, New Zealand, specializing in high-performance MIL-A-12560 sheets and plates designed for military, defense, and ballistic protection needs. This U.S. military-grade, quenched and tempered armor steel is renowned for its outstanding toughness, impressive hardness, and remarkable resistance to ballistic impacts and blast forces. Latham Steel is committed to meeting military specifications, ensuring precise dimensions, and delivering consistent mechanical performance. These plates are perfect for armored vehicles, security barriers, safe rooms, and protective structures that demand maximum durability, penetration resistance, and long-lasting reliability in tough and hostile environments.
MIL-A-12560 armor steel is made with controlled amounts of carbon, manganese, chromium, molybdenum, nickel, and other alloying elements to achieve top-notch hardenability and ballistic resistance. The steel is subjected to advanced quenching and tempering processes to reach high hardness levels (typically between 280–360 HBW, depending on the class), along with superior tensile strength and excellent impact toughness. It’s designed to resist cracking under shock loads and maintain stable performance across a range of temperatures. While it’s hard, it does have limited weldability, which requires careful heat-control procedures. The refined microstructure guarantees high durability, strong penetration resistance, and reliable mechanical strength for defense-grade applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
