Rene® 41
Rene 41® is a high-performance, precipitation-hardenable nickel-based alloy engineered for extreme environments. This nickel-chromium alloy offers outstanding high-temperature strength and excellent oxidation resistance in the temperature range of 1200°F to 1800°F (649°C to 982°C, making it ideal for use in aerospace and high-heat applications.
Rene 41® maintains its mechanical integrity under high stress and thermal cycling, offering a superior combination of creep resistance, fatigue strength, and surface stability at elevated temperatures. It is precipitation-hardened through a heat treatment process that enhances its strength characteristics while retaining corrosion and oxidation resistance.
