metengr,
we are going to weld a nozzle (9cr-1Mo)to a pump case (CA6NM) running at a temperarture of about 700F. No welding procedure qualification is required.
Thanks
Hi, I would like to know what would be the best PWHT temperature for a weld of A487 CA6NM with a 9Cr carbon steel.
I understand that the PWHT temp for the CA6NM is about 1150F and for the 9Cr is about 1350F
Thanks for your help
