11Ni-6Co-3.0Mo-0.9Ti Maraging Steel (var. 2)

This is a nickel-cobalt maraging steel, a precipitation-hardened iron-based superalloy engineered for extreme strength combined with fracture toughness. The alloy achieves its properties through age-hardening of intermetallic phases (primarily Ni₃Mo and related compounds) rather than carbon content, enabling superior toughness and weldability compared to conventional high-strength steels. Maraging steels of this grade are selected for aerospace structures, high-performance tooling, and defense applications where weight savings, fatigue resistance, and reliable performance under cyclic loading are critical—particularly where welded or machined components must maintain integrity at elevated temperatures or under impact conditions.
