Please explain "Grain Boundary Sensitization" term.

There is no ASTM equivalent for 15NiCuMoNb5.

As far as I know, we can hydrotest the vessel at 1.5 Design Pressure. You can easily calculate the hydrotest stresses in vessel at 1.5 times from any PV software like Compress. If your stresses are in permissible limit then you can test the vessel & piping at 235 psig. We had carried out hydrotest ...
