11Ni-13Co Maraging Steel (var. 6)

metal

11Ni-13Co Maraging Steel (var. 6) is a precipitation-hardening iron-nickel-cobalt alloy designed to achieve very high strength levels through controlled aging rather than carbon hardening, resulting in a martensitic structure with exceptional toughness and minimal distortion during heat treatment. This variant is employed in aerospace and defense applications where extreme strength-to-weight ratios, dimensional stability, and damage tolerance are critical—such as landing gear, rocket motor casings, and precision tooling—and is preferred over conventional high-carbon steels when engineers need high hardness without sacrificing fracture toughness or 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.
