Overview

As a leading supplier & manufacturer in China, AEETHER supply cost-effective Incoloy 945X Products.

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. 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.
