Dynamic Armor 500

Dynamic Armor 500® is a medium-carbon, low alloy, quenched and tempered steel plate product achieving a minimum of 477 Brinell hardness. The material is capable of meeting the requirements of MIL-DTL-46100E and a number of commercial armor specifications.

Mechanical Properties (typical)


Material will withstand up to 4*t (up to 0.3125 » thick) and 6*t (0.3126 – 0.500 » thick) bending. However, larger bend radiuses are recommended to reduce effect of cold working and highly localized residual stresses associated with bending.


Dynamic Armor 500® plates could be welded by common welding methods for high strength medium Carbon steels. Appropriate heat input controls should be used to prevent localized overheating. Preheating (although not required) can be done to eliminate surface moisture and to reduce thermal gradient. Preheat temperatures should not exceed 400°F to avoid Dynamic Armor 500® plates “softening”.

Ballistic Performance

Dynamic Armor 500® typically exceeds the required minimum V velocity of MIL-DTL-46100E by 100 – 150 feet per second. In appropriate thicknesses, Dynamic Armor 500® meets various protection levels of NIJ & EN 1063, and UL 752.

Dynamic Armor is not produced to a military standard. Dynamic Armor has been successfully tested against the firing requirements of various ballistic standards on a heat lot per thickness basis.
Ballistic tests are performed by 3rd party testing facility.
The chart above should be used as a guide to material selection, but in no way guarantees steel performance in these conditions.

Notice: Due to the wide variety of projectiles and the fact that ballistic performance is not a quantitative science, Dynamic Armor makes no guarantee or warranties as to the ballistic capabilities of Dynamic Armor plate. Dynamic Armor personnel will provide mill certificates and the independent 3rd party ballistic test results, on a heat lot basis, to demonstrate the typical ballistic performance against various ballistic standards, which can be used as a guide in material selection.
