Perforated Mars® 650 perfored: Ultra-High-Hardness perforated armor

Perforated Mars® 650 perforated is a ultra-high-hard (typical 650 HBW) protection steel offering uncompromising ballistic resistance performance, for use as add-on armor.
In the perforated version, holes are evenly distributed within the surface to interact with the diameter of the incoming threat. The use of specific perforation process leads to very good flatness, absence of HAZ and low residual stress.
