Mars® 300 Perforated

Perforated Mars® 300: ultra high-hardness steel (620 HB) for ballistic protection (add-on-armor)

Perforated Mas® 300 is a super high hard armour steel used for add-on-armour applications.
For the same level of protection, Perforated Mars® 300 is a light weight solution equivalent to weight composit solution like ceramic with a much better multi-hit capability and very easier possibility of integration than composit.
