Ultra High Hard Specialty Steel Armor

ATI 600-MIL® Ultra High Hard Specialty Steel is wrought Ni-Cr-Mo specialty steel designed for armor applications. The balanced composition of the alloy lends itself to good toughness relative to other "Ultra High Hard" alloys while maintaining ballistic resistance that satisfy demanding requirements.

Due to the unique composition of ATI 600-MIL®, liquid-quenching is not required to achieve the high hardness of this alloy rather; the high hardness is achieved via air-cooling. These processing practices result in low residual stresses leading to minimal plate distortion after mechanical cutting. Thermal cutting may produce some distortion, but is typically less than when thermally cutting liquid-quenched materials.
