René 41
VerifiedmetalUNS N07041
René 41 is a cobalt-based superalloy containing nickel, chromium, molybdenum, and aluminum alloying elements, designed for high-temperature structural applications in gas turbines and jet engines. The STA (solution-treated and aged) condition provides elevated-temperature strength retention and creep resistance up to approximately 1200°F (650°C), with excellent fatigue performance and oxidation resistance for demanding aerospace propulsion environments.

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.
