A low cost steel having high hardness, high strength, and high impact toughness is applicable for military articles such as armor plates, bodies of deep penetrate bombs, and missiles. After oil quenching, refrigerating, and low tempering, the new steel consisting of (% wt.): C=0.35, Cr=1.32, Mo=0.35, W = 0.52, Ni=2.66, Mn=0.85, Cu=0.51, Si=0.83, V=0.26, Ti=0.12, the balance essentially Fe and incidental impurities has HRC of 55, UTS of 301 ksi, YS of 233 ksi; Charpy V-notch impact toughness energy of 26 ft-lbs.
