I was looking for that data in the Code, I could not find it, hopefully someone has better luck and share the hardness data of this steel, with reference to the standard; On the other hand, when a pressure vessel carries the ASME stamp, the Authorized Inspector of the Authorized Inspection Agency necessarily has to intervene with your company has a contract, the Authorized Inspector has the obligation to advise and give you technical support.

--PWHT is followed spec, and WPS should be shown hardness test value.Sent from my Blackberry
For a pressure vessel designed with stamped under ASME VIII Div.1, there is a requirement that: "Hardness values should not exceed 200 brinell for the welds / material of shell."
Shell material is specified as SA516 Grade 70.
I am concerned the requirements for hardness and material will automatically require stress relief for all pressure vessel parts.
Would SA516 Grade 70 have hardness lower than 200 Brinell?
Thank you.
