What material is suitable for the fan housing of high-temperature gas (hydrogen-containing) fans? Can cast iron be used at 300 degrees (including resistance to hydrogen erosion and hydrogen embrittlement)? What considerations should be taken when selecting materials for hydrogen-containing high-temperature environments? I hope everyone can give me lots of advice! Thank you

Chromomolybdenum steel (medium-temperature hydrogen-resistant steel).

Can Q345 and cast iron be used? Many fan manufacturers quote cast iron

I don’t understand; there are no restrictions when it doesn’t come into contact with internal media.
