Does anyone have experience of selective corrosion and/or erosion/corrosion of Heat Affected Zone of carbon steel (ASTM A106 Gr. B)pipe weldment in sulfur dichloride service. I registered a greater amount of residual elements as Cu and Cr in corroded pipe in comparison with some uncorroded pipe...
Does anyone have experiece of Stress corrosion cracking of 304 Stainless steel components in steam reforming plant in low temperature shift converter section ?
Thanking in advance.

Does anyone know if it is reasonable to expect SCC problem in a coke oven gas primary cooler ? What kind of SCC can be expected (H2S, Carbonate,Alkaline.....)? It is true that a single side weld (not back gouged) can reduce the susceptibility to SCC problem in such a component ? In my opinion...
It is possible that a special HIC grade steel (clean steel) fails after few hours in NACE TM-0177 SSC test (method A) due to SOHIC phenomena? Does anyone know if this type of steel is more susceptible to such SOHIC phenomena than no extra-low sulphur steels ?

Does anyone know about corrosion problems of inconel alloys in CO/CO2 bearing gas (probable formation of nickel-tetra carbonyl)at temperature below 200°C.
