11Ni-9Co-0.8Ti Maraging Steel
metal11Ni-9Co-0.8Ti maraging steel is an ultra-high-strength iron-nickel alloy strengthened by precipitation hardening rather than carbon content, making it exceptionally tough and damage-tolerant at very high strength levels. It is used primarily in aerospace and defense applications where weight savings and reliable performance under extreme stress are critical—including rocket motor cases, landing gear, and structural components in high-performance aircraft. Engineers select maraging steel over conventional high-carbon steels when fracture toughness and dimensional stability during heat treatment are essential, and over titanium alloys when cost and machinability are competitive constraints.

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.
