280 Maraging Steel is a nickel-cobalt-molybdenum maraging steel (18% Ni, 8% Co, 5% Mo) used in aerospace and defense applications requiring very high strength with good toughness and damage tolerance. The maraged 900°F condition provides yield strengths around 280 ksi (1930 MPa) through precipitation hardening, maintaining relatively good fracture toughness and fatigue resistance compared to conventional ultrahigh-strength steels at equivalent strength levels.
