ABSTRACT:
The alloy of the present invention features controlled amounts of tin, nitrogen, and niobium and includes tin (Sn) in a range of greater than 0 to 1.50 wt. %, wherein 0.6 wt. % is typical. The alloy also has iron (Fe) in a range of greater than 0 to 0.24 wt. %, and typically 0.12 wt. %; chromium (Cr) in a range of greater than 0 to 0.15 wt. % and typically 0.10 wt. %; nitrogen (N) in a range of greater than 0 to 2300 ppm; silicon, in a range of greater than 0 up to 100 ppm, and typically 100 ppm; oxygen (O) in a range of greater than 0 and up to 1600 ppm, and typically 1200 ppm; niobium (Nb) in a range of greater than 0 wt. % to 0.5 wt. % and typically 0.45 wt. %; and the balance zirconium.
