RE: Tugsten carbide is NACE material
When we say NACE, we normally mean the valve body and trim.
Tugsten is coating on the ball and seat. And Tugsten is higher than NACE standards. So as long as the valve body and trim material is NACE standard, the valve is in NACE application.

i confused cause NACE have many criteria about material acceptance. like 22 HRC harness & at which partial pressure of H2s , different material should be used or not. so i could not understood about Tungsten carbide material acceptance standard.

To address the perceived thrust of the question, it would be useful to read the second paragraph of A.13.2.2 in Part 3, where the answer is readily obtained.
