10Ni-12Co Maraging Steel (var. 2)

metal

10Ni-12Co maraging steel is an iron-based alloy strengthened through precipitation hardening of intermetallic phases rather than carbon, making it exceptionally strong while retaining good fracture toughness and weldability. This variant is used in aerospace and defense applications—particularly landing gear, rocket motor cases, and high-strength fasteners—where ultra-high strength combined with damage tolerance and low distortion during heat treatment is critical. Engineers select maraging steels over conventional high-carbon steels or other superalloys when weight reduction and precision dimensional stability during manufacturing are priorities, and over titanium alloys when cost and machinability favor steel-based solutions.

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.
