Retains Strength at High Temperatures

René 41 is a nickel-based high temperature alloy. It retains high strength in the 1200/1800°F (649/982°C) temperature range. It is used in applications that require high strength at extreme temperatures.


  • ​Exceptionally high strength
  • Oxidation resistant through 1800°F


  • ​Because René 41 is stronger than regular steel it requires more powerful equipment to finish forming
  • Used in high strength, high temperature environments where oxidation resistance is of prime importance.
