For CO conversion in coal-to-gas production, are there heat exchangers of type C22, and what are they used for?

Our company manufactures static equipment for gasification; we have worked on several projects, and in the CO conversion process, some of them use heat exchangers made of Hastelloy C22, while others do not. I would appreciate some guidance from experts. Thank you!
It is mainly used in the main heat exchanger, where the gas exiting the saturation tower is heated in exchange for the reformate gas exiting the reformer. Since the semi-water gas coming out of the saturation tower contains a high amount of moisture and is therefore prone to corrosion, special materials are required; generally, the corrosivity decreases once the moisture has evaporated, and it seems that just one section is sufficient.
Thank you so much! ! ! ! The leader keeps asking me; now I can answer.
