AMS 5664 Turbine Blade Steel UNS N07718 AMS 5664E Hollow Square Bar
AMS 5664 Turbine Blade Steel UNS N07718 AMS 5664E Hollow Square Bar
Production Information
AMS 5664 is a nickel-chromium alloy, precipitation hardenable, with high creep rupture strength at elevated temperatures up to about 1300 °F (700 °C). AMS 5664 has a poor age hardening response, so annealing and welding will not spontaneously harden during heating and cooling. This alloy has excellent weldability compared to aluminum and titanium hardened nickel-based superalloys.
