René 95 is a high niobium and tungsten precipitation-hardened alloy developed for turbine discs and high-strength rotating hardware requiring excellent tensile and fatigue properties at intermediate temperatures. It is produced by powder metallurgy or cast routes for disc and structural applications where fine grain size and high strength are the primary requirements. Qualified under C5UFT77, René 95 serves aerospace and military propulsion applications requiring structural integrity under high rotational stress.
