Dear Friends
I need to qualify procedures for P5B (9Cr-1MoL) material urgently, at present I don’t have any material in stock
Since the preheat, interpass, interpass stress relieving and post weld temperature for P5B are too maintained strictly.
is the procedure qualification is possible by buttering? Did the secIX and Sec VIII Accepts.
Did anybody done it, if so how about the mechanical test results.
