    摘要： A composite material with a ballistic protective effect having a first, outer layer made of a first steel alloy and at least one second layer which is arranged under the first layer and is made of a second steel alloy. The composite material with a ballistic protective effect allows for a reduction in the weight or the wall thicknesses of the composite material in comparison to conventional composite ballistic materials, by utilizing a first steel alloy of the first layer that has the following alloy constituents in percent by weight (% by weight): 0.06%≦C≦1.05%, 0.05%≦Si≦1.65%, 0.3%≦Mn≦2.65%, 0.015%≦Al≦1.55%; Cr≦1.2%, Ti≦0.13%, Mo≦0.7%, Nb≦0.1%, B≦0.005%, P≦0.08%, S≦0.01%, Ni≦4.0%, and V≦0.05%, the remainder being Fe and inevitable impurities. The second layer of the composite material having a higher elongation than the first layer.
