What material should be used for valves dealing with concentrated sulfuric acid at around 200°C?
Thread Content
What material should be used for 99.5% concentrated sulfuric acid at around 200°C? What materials are 310M and 314M, and can they be used as materials for valves?
You can take a look at the corrosion manual; it contains information on materials suitable for use with sulfuric acid
In this case, it is necessary to use specially customized materials; Monel, Inconel, and Xinyi No. 1 should be able to meet your requirements, while 316L can only withstand acids with a concentration of less than 65%.
Apart from his 200°C value, which is a bit high, can’t sulfuric acid valves be made of carbon steel?
Generally, glass bottles, iron drums, and aluminum cans are used for transporting and storing concentrated sulfuric acid; you can refer to these as a guide
Please take a look at the link below containing data on sulfuric acid corrosion, and then tell us what material should be used for concentrated sulfuric acid at 200°C https://bbs.hcbbs.com/thread-1039675-1-1.html
Then tell me what to use? It’s supposed to be a discussion; I didn’t say it was a certainty. I also mentioned later that if 200°C is excluded, can’t carbon steel be used at room temperature? This is meant to be a discussion forum – why be so arrogant right from the start?
