Can 304 stainless steel be used to heat concentrated nitric acid?
Thread Content
Can concentrated nitric acid be heated after dilution, with the concentration remaining around 50% after dilution? Should 304 stainless steel pipes be used, and what should the heating temperature be at 95°? What material is best not to use?
Nitric acid is generally very effective for high-silicon cast iron
There is corrosion. In the absence of negative pressure, steel-lined PTFE pipes are used. Internally coated with tetrafluorine while still alive.
