Regarding the material selection for the catalytic deactivation agent tank
Thread Content
The catalyst uses an antimony-type passivator at a pH of 5–7. For our design, we have chosen 20R (Q245R); the tank dimensions are 1600*1500. I’ve just started working in the design department and don’t know much about materials yet, but it seems to me that the passivator is weakly acidic – should stainless steel be used instead? Under what circumstances are 20R and 16MnR typically used? Is there a book that explains what materials are usually chosen in what situations? Please recommend some to me!
You just need to take a look at books on material selection!
