[MW:34140] Re: Welding Consumable - SA 479 410SS (Control valve seal retainer)

You can use E410 and sometimes E309, But for your case, my best suggestion is ERNiCrMo-3 because your service operation is associated with corrosion and erosion and further there is carbon steel material there that will be joined to SS.

ER CrNiMo-3

GTAW if possible

Preheat for thk>1" about 100 C

if you wanna healing the surface use AC plus 50-50%
