15Ni-8Co-2.9Mo-0.8Ti Maraging Steel

metal

15Ni-8Co-2.9Mo-0.8Ti is a high-strength maraging steel designed for applications demanding exceptional strength combined with good toughness and damage tolerance. The nickel, cobalt, and molybdenum additions enable precipitation hardening during aging, while the low carbon content minimizes brittleness—making this alloy particularly valuable in aerospace and defense where weight savings and reliability are critical. Engineers select maraging steels over conventional ultra-high-strength steels when fracture toughness and fatigue resistance must be maintained at very high strength levels.

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.
