280 Maraging Steel Maraged 900°F
Verifiedmetal280 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.

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.
