18Ni-13Co-2.1Mo-1.9Ti Maraging Steel

18Ni-13Co-2.1Mo-1.9Ti is a precipitation-hardening (maraging) steel engineered for exceptional strength-to-weight ratio and toughness without requiring quenching, achieved through controlled aging of a soft, machinable austenitic matrix. This alloy is critical in aerospace and defense applications where extreme strength combined with damage tolerance and dimensional stability are non-negotiable, particularly in landing gear, missile bodies, and structural forgings where traditional quenched-and-tempered steels would be brittle or difficult to machine to final dimensions.
