5.Structure
Iron base alloy, solid solution strengthening.
In addition to the austenitic matrix, there are 2% of the primary Z phase existing in the form of inclusions.
6.Applications
Provided in the form of after-burners aircraft engine components working until 950 ℃, such as load bearing elements,
structure, shell, installation side,etc.
The short-time product artifacts until 1000℃.
Can be used as substitute of a nickel base alloy GH3044, GH3039, GH3030.
