HEAT EXCHANGER MATERIAL
(OP)
I have a "FLUE gas" plate heat exchanger. Temperature of Flue gas is 400 °C (inlet) 200°C (outlet). Is it enogh to use a common carbon steel like ASTM A 516 Gr.60? Or is better to use high temperature carbon steel like ASTM A 387 Gr.11/22etc.?

I am puzzled by your post. Are you building a plate Hx or repairing one?
Be careful of the cold end where the air enters - that is to say inspect it often. It can get below dew point at that point on the flue gas side.

These normally work in the "inches of water" pressure range so B&PV or API codes don't normally apply.
Corten is commonly used when the materials are not SS.
