19Ni-14Co-1.8Ti Maraging Steel

metal

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.

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
