14Ni-15Co-1.4Ti Maraging Steel

metal

14Ni-15Co-1.4Ti is a ultra-high-strength maraging steel engineered for extreme performance in weight-critical applications where both strength and some ductility are essential. This nickel-cobalt-titanium system achieves its strength through precipitation hardening during aging rather than carbon content, enabling a combination of high strength with improved toughness and low distortion during heat treatment compared to conventional tool steels. It is primarily used in aerospace, defense, and tooling industries where designers need to reduce component mass while maintaining reliability under severe loading conditions.

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.
