Chloride-resistant shaft
Thread Content
I would like to ask everyone: what grade of material is suitable for use in shafts that need to resist chloride corrosion? Thank you!
The volume ratio is 4%. Currently, 2205 duplex steel is planned to be used, but there are concerns that its stiffness may not be sufficient. I wonder whether the precipitation-hardening stainless steel 17-4 can withstand chloride corrosion under these operating conditions
A276 Type S31803, A276 Type S32760
I just checked, and S31803 is the same as 2205
Wouldn’t it be better to simply replace it with a fluorine-lined pump? P
At normal temperatures, 316L is sufficient; however, it is a relatively soft material. Carbon steel can also be used, and no safety issues will arise. But in the case of overall corrosion, it may be necessary to replace the shaft regularly
