Re: [MW:16287] Regarding welding of material grade SA 240 GR 410 TO SA 240 GR 410 and SA 240 GR 410 TO SA 105
what is your construction code? refer Table A.2 of API RP 582 for
filler metal selection
Note that the HAZ on 410 side is more susceptible to cracking (due to
hard martensitic zone)
Refer Table UHA 32 (P Number 6) of ASME Sec VIII Div 1 for
preheat/PWHT recommendations
