I know this is an easy one for you gentleman; could
ASTM A105 be used as a replacement for ANSI 1026.
The 1026 material (normalized forging)is on an 18 week backlog, engineering wants to see if A105 would make a good replacement. The forging requires yield and CVN restrictions (nothing high)...
In ASME IX, QW-163, does that interpret as one single
discontinuity exceeding 1/8", and not a collection of discontinuities (say five 1/16" discont.)exceeding 1/8".
So in other words,the bend specimen can have many discontinuities as long as no single one exceeds 1/8".
Gentleman, I had submmited a PQR & WPS to a 3rd party surveyor for review; these were in accordance with ASME IX. The PWHT time on the PQR is 2.5 hrs. at 1150 F, I
had stated on the WPS that the minimum and maximum time
at temperature allowed would be 2 to 2.5 hrs.(my interpertation of QW-407.2)...
