Which Valve for Nitric Acid Service?

Another issue people struggle with concerning nitric acid is whether they should use the low-carbon grades 304L,316L or the cast equivalents CF3 and CF3M.The concern is that nitric acid is a strong oxidizing acid that can cause intergranular corrosionone way to minimize the susceptibility to intergranular corrosion is to use the low Stainless Steel Application in Sodium Hydroxide Production Actually,all stainless steels have good corrosion resistance in dilute nitric acid.18-8 Cr-Ni Austenitic stainless steels such as 06Cr19Ni10(304),022Cr19Ni10(304L),06Cr18Ni11Ti(321) all have good corrosion resistance to dilute nitric acid,hence extensively used in nitric acidStainless Steel 304L - an overview ScienceDirect Topics5.1 Stainless Steels for Nitric Acid Application.AISI type 304L SS is extensively used for fabrication of vessels,tanks,piping,and equipment in reprocessing plants.However,in highly oxidizing nitric acid environment,SSs are susceptible to severe intergranular corrosion (IGC),even if the steels are not sensitized [11,12,63].
