A516 Gr 70 Welding Hardness
(OP)
Is there a hardness limitation imposed on vessel production welds? I "think" hardness limitation exists for vessels in sour service as required by MR0175, but is there a similar limitation for sweet hydrocarbon service? I keep hearing 248 HV being mentioned but I am not sure of truth in it or where it originated from.
Thanks again.

Don't know offhand if Sec VIII, Div 1 imposes limits or not.
What are you working to?
