Mars® 300

Mars® 300: Ultra high-hardness steel (600-640HB) for ballistic protection

Mars® 300 is a super high hard armour steel (620 HB).

Mars® 300 presents a very high level of ballistic performances in comparison with standard armour materials.

Mars® 300 can be used for a wide range of applications: individual protection, light armour for helicopter protection, removables for vehicles, add-on-armour, heavy armour for MBT protection against kinetic energy projectiles and shaped charges.
