280 Maraging Steel
VerifiedmetalUNS K92940
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.

Quality & Standards
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.
