Incoloy 945/945X
INCOLOY alloy 945 products are available in several strength grades. Conventional annealed and aged alloy 945 products exhibit a minimum yield strength of 125 ksi. A high strength grade of the alloy, designated INCOLOY alloy 945X, exhibits a minimum yield strength of 140 ksi. Limiting mechanical properties are presented in Table 13. Comparative data are presented in Tables 7 and 8. The strength of alloy 945X is also higher than that of alloys 718, 725, and 925. In addition, cold worked and directed aged products are available with even higher levels of strength for applications such as shafting. Limiting mechanical properties are reported in Table 14 and comparative strength levels are found in Tables 9 and 10.
