gas turbine's exhaust internals material

[suraiya]

Which one between SS304, SS304L and SS409 is the better material for internal parts of gas driven turbo-generator exhaust. The application is for an offshore gas platform. As such, it shall suit a marine environment,ie. exposure to high humidity and saltwater/chloride environment.

you might consider Inconel over Stainless Steel.
