I'm on an oil & gas project and we have stainless steel types, 304H, 304L, 316, 316L, & 321.

As these types are all P8 Group 1, could weld procedure qualification in one type, qualify all types and satisfy ASME IX requirements?

If so, which type is recommended to be used for the qualification?

A PQR made with P8 would generally qualify for all P8 materials per ASME IX.
