11Ni-13Co Maraging Steel (var. 2)

metal

11Ni-13Co Maraging Steel (var. 2) is an iron-nickel-cobalt maraging steel, a precipitation-hardened ultra-high-strength alloy designed to achieve exceptional strength through aging heat treatment rather than carbon content. This composition variant is used in demanding aerospace, defense, and tooling applications where extreme strength combined with reasonable toughness is critical—particularly in rocket motor cases, landing gear, and high-performance dies where weight savings and fatigue resistance justify the material cost.

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.
