EN 12952-2 Flanges and fittigs materials
(OP)
Hello,
In table A.1 of Annex A we can found the list of european standardised steels for construction of water-tube boilers.
I want to use P195GH EN 10216-2 for the tubes, and P245GH for flanges, as far as the material is included in EN 10222-2, but is not listed in Table A.1.
If I can't use this material wich one can I use to replace it?
Forgings grades allowed by the table A.1:
X16CrMo5 1
X20CrMoV11-1
X10CrMoVNb9-1
14MoV6-3
11CrMo9-10
16Mo3
13CrmO4-5
P285NH or QH
P355NH or QH
P420NH or QH
Thank you for your help.

What is your PS and TS? I could advice a material choise though, because I have some experience in high pressure high temperature steam piping.
