UT standard for monel shell plate

[212197]

I have to make one shell for critical application.
plate to be used for shell is 13 mm. Material is SB 127 (MONEL).

I want to examine the plate by ultrasonic test. SB 127 does specify military standard for UT.
I WANT TO KNOW WHICH ASTM/ASME STANDARD TO BE USED FOR CARRYING OUT MOENL PLATE'S UT.

For plate of that thickness you will not have issues using either SA-435 or SA-578. You may want to consider SA-578 supplementary requirement S1 if it is a critical application.

But SB 127 does not specify SA578,435 as reference standard. Secondly title of SA435,578 indicates that it mainly used for steel(ferrous). Please comment

Assuming you are working to the ASME Boiler & Pressure Vessel Code, the UT specifications are called out in Section V, Article 5 not the Section II base material specification.

Section II also indicates reference standards in para "REFERENCE" under each specification.
I did not find any article/reference for standard for UT of Monel plate in Article 5.
