[Muhammad Ijaz]

Dear Sir,

Please confirm that "SA-193 Gr. B8" bolts means only "SA-193 Gr. B8 Class 1" bolts or it may be "SA-193 Gr. B8 Class 2".

Regards

Technically, neither, since gr B8 has 4 classes. Refer to table 1 of SA-193. If neither is specified, Id assume class 1, but thats me. Someone else may think different and assume B8-2 if thats his typical scope of work. Just specify it as B8-1 or B8-2.
