250 Maraging Steel

Verifiedmetal
UNS K92890

250 Maraging Steel is a nickel-iron-cobalt alloy designed for ultra-high-strength aerospace and defense applications, offering yield strengths exceeding 200 ksi when age-hardened. The material provides exceptional toughness-to-strength ratios, low thermal expansion, and excellent dimensional stability, making it suitable for critical structural components, tooling, and pressure vessels in extreme-performance environments.

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.
