  • Steel compositions, methods of forming the same, and articles formed therefrom
    Patent number: 8361254
    Abstract: Maraging steel compositions, methods of forming the same, and articles formed therefrom comprising, by weight, 15.0 to 20.0% Ni, 2.0 to 6.0% Mo, 3.0 to 8.0% Ti, up to 0.5% Al, the balance Fe and residual impurities. The composition may be a first layer of a composite plate, and may have a second layer deposited on the first layer, the second layer having a composition comprising, by weight, 15.0 to 20.0% Ni, 2.0 to 6.0% Mo, 1.0 to 3.0 Ti, up to 0.5% Al, the balance Fe and residual impurities. The first layer may have a hardness value ranging from 58 to 64 RC, and the second layer may have a hardness value ranging from 48 to 54 RC. The first layer may be formed employing powdered metallurgical techniques. Articles formed from the compositions include armored plate.
