280 Maraging Steel aged at 900°F is a nickel-cobalt-molybdenum maraging steel offering ultra-high strength (typically 280 ksi yield) with exceptional toughness and fracture resistance, primarily used in aerospace structures, die-casting dies, and precision tooling. This aging condition provides optimal strength-to-toughness balance through controlled precipitation hardening, with good dimensional stability and machinability.
