17Ni-12Co-2.3Mo-1.8Ti Maraging Steel
metal17Ni-12Co-2.3Mo-1.8Ti is a precipitation-hardening maraging steel engineered for ultra-high strength with controlled toughness, relying on intermetallic phase formation (rather than carbon) to achieve its strength profile. This composition is used in aerospace structures, high-performance tooling, and precision instrumentation where weight savings and fatigue resistance are critical; it is particularly valued over conventional steels because it combines exceptionally high strength with better fracture toughness and weldability due to its very low carbon content, making it suitable for thick-section applications that would become brittle in carbon-hardened alloys.

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.
