A 45%*ao acid aqueous solution (with a absolute pressure of 0.7 MPa and a temperature of 40–60 degrees). How can the boiling point be determined? Thank you all; I am grateful.
316L and 321 both work; high-quality 304 is also an option
Have you designed devices using such media, or do you have experience in using materials for devices in this type of medium? Is it very effective?
Previously, heat exchangers made of S30408 were used, and an intergranular corrosion test using the 65% nitric acid method was required. If I do it now, I might choose S32168.
Why was it changed to S32168? Did users find that the regular 304 didn’t perform well?
Ask the design institute about the process for this. They know best
There is no design institute; the owner is L
All of Jiangxi Shilong’s *ao acid an equipment is made of S32168; this material is generally used in this industry, with 304 being used very rarely.
