18Ni-7Co-3.1Mo-1.1Ti Maraging Steel
metal18Ni-7Co-3.1Mo-1.1Ti is a precipitation-hardening maraging steel engineered for extremely high strength with retained toughness through controlled aging of a low-carbon, nickel-rich matrix. This alloy is used in aerospace, defense, and high-performance tooling applications where weight savings and reliability under extreme stress are critical, competing with titanium alloys and other superalloys where cost and machinability are also constraints. Its combination of very high strength, good ductility, excellent weldability, and superior toughness compared to conventional hardened steels makes it preferred for components requiring damage tolerance and fracture resistance alongside extreme load capacity.
