17Ni-15Co-2.4Mo-1.8Ti Maraging Steel

metal

17Ni-15Co-2.4Mo-1.8Ti is a precipitation-hardening maraging steel engineered for ultra-high strength with excellent toughness and fatigue resistance. The high nickel and cobalt content, combined with molybdenum and titanium additions, enables age-hardening to achieve exceptional strength levels while maintaining sufficient ductility for structural integrity. This grade is selected over conventional steels and aluminum alloys in aerospace and defense applications where weight savings, damage tolerance, and reliability under extreme loading are critical—particularly where traditional high-strength steels would be too brittle or where aluminum lacks adequate strength margins.

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.
