11Ni-6Co-3.0Mo-1.5Ti Maraging Steel

metal

11Ni-6Co-3.0Mo-1.5Ti maraging steel is an iron-nickel superalloy that achieves ultra-high strength through precipitation hardening of intermetallic phases rather than carbon content, making it exceptionally strong while maintaining good fracture toughness and machinability in the annealed condition. This grade is employed in aerospace and defense applications where weight savings and reliability at high stress are critical, including rocket motor cases, landing gear, and structural components that demand the strength-to-weight ratio and toughness balance that conventional hardened steels cannot match. Engineers select maraging steel over competing high-strength materials when component geometry or manufacturing constraints favor steel's weldability and damage tolerance, though the material commands premium cost and requires careful thermal processing to realize its full potential.

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.
