250 Maraging Steel Maraged 900°F
Verifiedmetal250 Maraging Steel is an iron-nickel-cobalt alloy (18% Ni, 8-9% Co, 3-5% Mo) aged at 900°F to achieve ultrahigh strength (typically 250 ksi yield) with excellent toughness and fatigue resistance; widely used in aerospace applications including landing gear, fasteners, and structural components requiring high strength-to-weight ratio and damage tolerance.

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.
