19Ni-14Co-1.8Ti Maraging Steel

19Ni-14Co-1.8Ti maraging steel is an ultra-high-strength iron-nickel alloy hardened by precipitation of intermetallic phases rather than carbon, resulting in a martensitic matrix with exceptional strength and toughness at relatively low carbon content. It is used in demanding aerospace, defense, and precision engineering applications where extreme strength-to-weight ratios, dimensional stability, and fracture resistance are critical, such as rocket casings, landing gear, and high-performance tooling; this alloy family is preferred over conventional tool steels and other ultra-high-strength materials when designers need to combine very high yield strength with adequate ductility and minimal distortion during heat treatment.
