Subject: [MW:15323] Alloy Material Hardness
We're going to construct a new power station; according ASME sect B31.1.
We have many alloy steels (Grades P11, P91, P22 material) welded joints. Even when PWHT is performed, our client say that we don't have to perform hardness test.
Even NDE is the client scope, i'm searching for support from code to have exact infiormation, uis it mandatory ?
Need your help.
