11Ni-6Co-3.0Mo-0.9Ti is a nickel-cobalt maraging steel, a precipitation-hardened iron-based superalloy designed to achieve ultra-high strength through aging heat treatment rather than carbon hardening. This composition sits in the 1100–1200 MPa strength class and is engineered for applications demanding exceptional strength-to-weight ratio, fracture toughness, and dimensional stability in critical aerospace and defense components. It combines the benefit of martensitic steel processing with cobalt and molybdenum precipitation hardening to deliver high performance at modest weight penalties compared to titanium alloys or bulk superalloys.
