10Ni-13Co Maraging Steel (var. 3)

metal

10Ni-13Co Maraging Steel (variant 3) is a precipitation-hardening iron-nickel-cobalt alloy engineered for ultra-high strength with good toughness and ductility. This variant sits in the maraging steel family—materials that achieve strength through intermetallic precipitation during aging rather than carbon hardening, making them machinable in the annealed state and weldable without brittleness. Industrial applications focus on aerospace, defense, and high-performance tooling where the combination of extreme strength, impact resistance, and fatigue durability are critical; it is particularly valued in landing gear, rocket motor casings, structural fasteners, and premium die-casting dies where conventional high-carbon steels would be too brittle or difficult to machine.

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.
