Reply to the question of Mr K D Pandithan

As per the recommendation of Special Metals--US A

 Following grades are recommended for dissimilar welding of 625 to grade 310 S Steel

1--INCONEL 617==ERNICRCOMO-1       FOR HIGHEST TEMP SERVICE (INCO 617 HAS HIGH COBALT CONTENT)

2--INCONEL 625==ERNICRMO-3       FOR MEDIUM TEMP  SERVICE 

3--INCONEL 82=ERNICR-3               FOR LOWER SERVICE TEMP
