Gents,

I have created an SR officially thru Hexagon support.

And received the following reply:

"As long as the material vendor confirms the allowable in A1 can be used for high-pressure piping(Table K1) and the client agrees with the allowable stress(from table A1), you can always use that allowable. This allowable stress is used in thickness calculation and validation as well. So you should be careful while considering the material allowable. You need to add B 444 N06625 in the material database and select that material during analysis."

Does anyone has additional comments/ideas on this?
