17Ni-12Co-2.4Mo-2.1Ti Maraging Steel

metal

17Ni-12Co-2.4Mo-2.1Ti is a precipitation-hardened maraging steel engineered for extreme strength with controlled ductility. The high nickel and cobalt content, combined with molybdenum and titanium, enables age-hardening to achieve exceptional strength-to-weight ratios while maintaining reasonable toughness—a combination that makes it superior to conventional high-strength steels in demanding aerospace and defense applications where weight reduction is critical without sacrificing structural reliability.

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.
