14Ni-15Co-0.5Ti Maraging Steel

metal

14Ni-15Co-0.5Ti maraging steel is an ultra-high-strength iron-nickel-cobalt alloy that hardens through precipitation of intermetallic phases during age-hardening rather than carbon content, enabling excellent combination of strength and toughness with minimal distortion during heat treatment. Maraging steels are used in aerospace (landing gear, structural forgings), military ordnance (gun barrels, missile casings), and precision tooling where weight savings and dimensional stability are critical. This nickel-cobalt composition is chosen over conventional maraging grades when maximum strength density and corrosion resistance are required, and it offers superior performance to conventional high-strength steels in applications where post-heat-treat machining and welding precision cannot tolerate significant distortion.

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.
