May I ask your valuable inputs with regards to my queries.
Base on the attached report, the actual value of %Cr is 20% as per PMI and the value of %Cr in ASME Sec IIA. Now my question, is this acceptable or not ?
Thank you in advance.
Regards,
Mac

You can make a weight analysis to insure the real content of Cr.
Knowing that this test is a destructive test.
thank you

10% deviation in parant metal and 12.5% deviation in Weld acceptable in PMI results

Kindly get client specification for the same as they have mentioned the acceptance criteria in the same.
Many clients are acceptable the tolarnce range is +- 10%.
In this case Chromium range between 19.8 to 28.6 is acceptable.

You can refer PFI ( Pipe fabrication Institute ) or 10 % bi lateral tolerance of actual alloy content from code for the base metal.
