14Ni-9Co-3.0Mo Maraging Steel

metal

14Ni-9Co-3.0Mo is a nickel-cobalt maraging steel—a precipitation-hardened iron alloy designed to achieve very high strength through aging heat treatment rather than carbon hardening. The high nickel and cobalt content, combined with molybdenum and trace amounts of titanium, aluminum, and vanadium, enables strength development without brittleness, making it suitable for demanding applications requiring both high strength and toughness. This alloy is used in aerospace, defense, and precision manufacturing where weight savings and reliability are critical, and is valued over conventional high-strength steels when superior combination of strength, ductility, and fatigue resistance is needed.

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.
