Ammonia flows through the tube side; does ammonia have corrosive properties? Is 16MnR a suitable material?

For liquid ammonia and gaseous ammonia, as long as there is no water present, carbon steel is sufficient; since it is a pressure heat exchanger, 16MnR can be used

16MnR works; actually, 20R also works

Thank you all :) Just add the corrosion allowance, haha
