Hardness Test Value of A106-Gr. B material
Hardness Test Value of A106-Gr. B material
(OP)
I would like to know where can I find the required maximum hardness test value(HB) of carbon steel(A106-B) after post weld heat treatment. Is this mandatory to carry-out in the preparation of welding procedure, if the design codes are for ASME I, B31.1 and B31.3?

No, not for the listed Codes above.

It all depends on the end user's requirements. If they require hardness testing, it needs to be done and they should spec the maximum allowed.
