18Ni-8Co-2.9Mo-0.8Ti Maraging Steel

metal

18Ni-8Co-2.9Mo-0.8Ti is a precipitation-hardening maraging steel engineered for extreme strength-to-weight performance without relying on carbon hardening. The cobalt, molybdenum, and titanium additions enable age-hardening through intermetallic precipitation, yielding a martensitic steel that maintains toughness and ductility even at ultra-high strength levels. This material is chosen for critical aerospace and defense components, precision tooling, and sporting equipment where lightweight design, damage tolerance, and repeatability cannot be compromised—applications where conventional high-strength steels would be too brittle or require prohibitive thickness.

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.
