I would like to ask the forum members: what are the differences between 321 stainless steel pipes and 12Cr1MoVG alloy pipes in terms of use under temperature and pressure conditions, given that the medium is ammonia synthesis gas? I hope everyone can discuss this

The latter is a material specifically designed for high-temperature and high-pressure steam

Refer to GB/T 20801.2-2006 Code for Pressure Piping – Industrial Piping – Part 2: Materials

I think for this operating condition, more consideration should be given to the transmission medium... Isn’t it more important to take into account the corrosion resistance of the material?
