A-286 STA
VerifiedmetalA-286 is an iron-nickel-cobalt superalloy (Fe-Ni-Co base with Ti, Al, Mo, V, Cr) solution heat-treated and aged (STA) to provide sustained strength up to ~700°C, offering yield strengths of 170–200 ksi with good fatigue resistance and oxidation protection for jet engine components, fasteners, and high-temperature structural applications. The STA condition delivers optimal tensile properties and bearing strength characteristics while maintaining ductility suitable for aerospace fastening and engine hardware applications.

Export Control
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.
