11Ni-10Co-1.3Ti Maraging Steel

metal

11Ni-10Co-1.3Ti maraging steel is an iron-nickel-cobalt precipitation-hardened alloy designed to achieve ultra-high strength through controlled aging rather than carbon content, making it exceptionally clean and ductile compared to conventional high-strength steels. This material is widely used in aerospace, defense, and space applications—including rocket motor cases, landing gear, and structural components—where engineers require the combination of very high strength, excellent fracture toughness, and low distortion during heat treatment. The cobalt and titanium additions enable precipitation hardening to very high strength levels while maintaining weldability and machinability that would be impossible in carbon-hardened alloys of equivalent strength.

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.
