The working medium is unknown; it’s impossible to determine!
If the medium is not special, CrMo steel should work just fine.
Chromomolyvanadium steel: 12Cr1MoVG, commonly used in power station valves
When carbon steel materials are at high temperatures, their performance deteriorates significantly, and many regulations can no longer be applied. I think CrMo steel is quite suitable
The material should be selected based on the conditions of the medium; pressure and temperature affect the thickness of the material
It’s probably 12Cr1MoVG, but I’m not entirely sure what the allowable stress at 550 degrees can be
