Mars® 190

Mars® 190: RHA steel (< 430 HB) for ballistic protection

Mars®190 has been studied for vehicle structures (main battle tanks, armour personal carriers…), stationary protection (buildings, sentry boxes, observation posts…) and targets.
Mars® 190 has a very great adaptability, combining easy workability even in thick thicknesses, with good ballistics properties against all ammunitions.
