10Ni-7Co-1.2Mo Maraging Steel

metal

10Ni-7Co-1.2Mo maraging steel is an iron-nickel-cobalt precipitation-hardening alloy engineered for extreme strength combined with reasonable toughness, achieved through controlled aging rather than carbon hardening. This ultra-high-strength steel is primarily used in aerospace and defense applications—including rocket motor casings, aircraft landing gear, and precision tooling—where weight savings and damage tolerance are critical. Engineers select maraging steels over conventional high-strength steels when applications demand superior fracture toughness at very high strength levels, minimal distortion during heat treatment, and excellent machinability in the solution-annealed condition.

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.
