Type 347 is a stabilized austenitic stainless steel similar to type 304 with an addition of Columbium and Tantalum. The columbium serves to produce a stabilized type of stainless steel which is immune to chromium carbide precipitation. This type of grades are thus recommended for parts fabricated by welding which cannot be subsequently annealed ...

Abstract. A new prediction tool was developed for sulfidation corrosion applied in crude units. The corrosion rate of sulfidation is predicted using the total sulfur concentration and temperature by the modified McConomy curves. However, the corrosion behavior in crudes even with the same total sulfur concentration is sometimes different.

The metallurgy of the unit is predominately SS347 and SS316. The areas I'm mainly concerned about are the wash water injection point which is at elevated temperatures (~250F) and dead ends. Wash water is injected in large excess so there is no chance of drying out. Heat tracing maintains temperature above water dew point in the hotter parts …

we are trying to weld a bush (SS347) and flange (SS304) together in TIG welding, observing a crack, can any one suggest to how to overcome this problem. You will need some 347 rod. Are you sure your flange is not 303 that will cause your cracking for sure. I cannot see why 347 and 304 would be a problem. Only 347 and 303.
