Hi
Doing a quick dilution calculation with assumed parent and consumable chemistry the resulting weld material will have approximately 5% ferrite. At 760deg C (1400 deg F) you may form some sigma which will reduce the notch toughness at ambient. Given your description since this “plug” is acting...
Hi
It does not really matter if this is standard 9CrMo or 9CrMo modified (P91). The power generation industry has many years of experience with dissimilar joints and have used nickel based consumables ie AWS A5.11 ENiCrFe-3 SMAW, AWS A5.14 ERNiCr-3 GTAW.
As 310 is fully austenitic there will be...
Thanks for the link. With respect to your application 125ksi/862MPa yield from a Super Duplex is not feasible!. I do not know what your application is but if you want this level of yield from a stainless steel type and resistance to intergranular and pitting corrosion you may consider looking at...
