Dear Experts ,

We are using SS410S CLAD in Coke Drum at 450 degree temp.

Is IGC test required for SS410S material ? at present there is no requirement of IGC testing for SS410S in coke drum cladding in industry .

 As per my understanding, IGC happens in ferritic SS as well if they are exposed to high temp(450 in my case) in operation , welding or PWHT. So why SS410S is not tested for IGC as per A763 ?

How IGC is different in ferritic SS than in Austenitic SS ?

Thanks and Regards,

Ronak Patel.
