Ti-45Nb (Gr36)
Ti-45Nb is listed is ASTM specification as Gr36. This alloy has great compatibility and resistance to ignition in oxygen rich environments compared to commercially pure titanium. The niobium significantly increases the threshold oxygen pressure and process temperature for ignition. Strength is in the medium range, but the elastic modulus is 40% below that of commercially pure titanium and most alloys.
