10Ni-13Co Maraging Steel

metal

10Ni-13Co maraging steel is a high-strength, low-carbon iron-nickel-cobalt alloy designed to achieve exceptional strength through precipitation hardening rather than carbon content, making it highly machinable in the annealed condition before heat treatment. This material is primarily used in aerospace and defense applications where extreme strength combined with reasonable toughness and machinability is critical—including rocket motor cases, landing gear components, and high-performance tooling. Engineers select maraging steel when conventional high-carbon steels or other super-alloys prove either too brittle to machine, too expensive, or unable to deliver the required strength-to-weight ratio in complex geometries.

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.
