Acceptance criteria - Hardness super duplex welds
Acceptance criteria - Hardness super duplex welds
(OP)
New specs requires:
Maximum hardness value shall not exceed 310HV10 - this is for the Welding Procedure Qualification.
In previous project acceptance criteria was 350HV10
I believe it can be difficult to achieve 310HV10
Do somebody has such as experience..some advise?

310HV10 is ok for 22Cr but difficult for 25Cr.
Not sure what your application is but certainly in my field DNV-OS-F101 allows up to 350HV10; you could use this as the basis of your TQ.
