10Ni-13Co Maraging Steel (var. 2)

10Ni-13Co Maraging Steel (variant 2) is a precipitation-hardening martensitic steel characterized by high nickel and cobalt content, designed to achieve ultra-high strength through age-hardening rather than carbon content alone. This alloy variant is employed in aerospace and defense applications where exceptional strength-to-weight ratios and excellent toughness are critical, particularly in components requiring both high load-bearing capability and resistance to brittle failure. The high cobalt addition distinguishes this variant as optimized for demanding service conditions where conventional high-strength steels would be inadequate, making it a preferred choice over lower-cobalt maraging grades or competing materials like titanium alloys when weight is less constrained than ultimate strength and damage tolerance.
