sa-182-f316 <=5 vs sa-182-f316<=5 low stress compress codeware

[fenil11]

Hello,
Did anyone came across the design for the pressure vessel which has been used 316/316L dual rated material. we have an issue with the blind material. In code compress software we used ug-34 cover as option for the closure and used sa-182-F316 <=5 material on it. but my senior told me to used sa-182-f316 <=5 (low stress) and mentioned to me that you can't used this material due g5 note in it. Do anyone know what is the difference between sa-182-f316 <=5 vs sa-182-f316<=5 low stress material in compress code ware??
Thanks,

The difference can be found in ASME Section II Part D Table 1A Note G5.

Your senior is correct to say the low stress option should be used for a blind flange.
