Hi,
How to comply with sour service related 310HV limit on 25Cr Duplex?
Tried a TQ as suggested on thread330-344142, but in vain.
Different PQR has been produced for this scope, with very good result except for higher than 310HV hardness values on the root zone.
Has anyone here experience with such low requirements?
