17Ni-8Co-3.0Mo-1.8Ti Maraging Steel
metal17Ni-8Co-3.0Mo-1.8Ti is an ultra-high-strength maraging steel engineered through age-hardening precipitation of intermetallic phases rather than carbon-based hardening, enabling it to achieve exceptional strength with minimal brittleness. Widely adopted in aerospace and defense applications—particularly for critical structural components, landing gear, rocket motor casings, and aircraft fasteners—this alloy is chosen when weight reduction and damage tolerance are as important as absolute strength, offering superior toughness compared to conventional heat-treated steels at comparable strength levels.
