René 41 STA
VerifiedmetalRené 41 STA is a nickel-base superalloy (Ni-Co-Cr-Mo-W-Al-Ti) in solution heat-treated and aged condition, designed for high-temperature structural applications in jet engines and gas turbines operating up to 1100°F (593°C). The STA condition provides optimized strength and creep resistance through controlled grain structure and precipitation hardening, with excellent bearing strength and fatigue performance in bar, forging, plate, and sheet forms.

Environmental
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.
