HRSG Stack Silencer Material

[TAGE]

Dear Sir
Does anyone have any idea about the normal (suitable) material for the HRSG stack silencer or so called "buffer" installed INTERNALLY inside the stack?
Please share me your experience regarding this matter.

Thanks for your kind help
Best Regards

If the temperature is less than about 550F, 304 SS should be suitable.

I have encountered thin walled SS liners used in power generating service
